WE'RE never GETTING OUT OF RUINED HOME WITH THIS ONE 🔥🔥🔥 As we continue working on low-priority sprite revamps alongside more important v3.0+ tasks, we've been finalizing our Aaxel resprite! Still subject to change.

Here's a sneak peak of a future update! All of the Boogiemen's new battle sprites are finished and implemented in-game -- all we have to do is polish things up, fix some issues, and manually backport everything from the Demo v3.0+ branch to Demo v2.0's. Then, the new music... and it's good to go!

All new sprites for the Boogiemen (excluding a new fight cloud animation at the end) are finished and being implemented in-game! We're currently nearing completion with this on the Demo v3.0+ branch, and will need to backport everything to the 2.0 branch afterwards.

Here's a quick bulletpoint list going over the rest of what we covered, but didn't want to show anything off for:

That was a lot! To finish off this section, here's a few more things we've been working on -- we either don't want to show these off currently, or feel there isn't much point to showcasing them:

- Reworks to Bugerpant's overworld sprites for consistency with his look from Deltarune (still in early stages, low priority given how many sprites we'd need to change.)

- Reworks to Mad Dummy's battle sprites for consistency with our current art style (still in early stages, higher priority given Dummy-related content in Crystal Springs.)

- Reworks to Flowey's facial expressions (incl. number thereof) to better differentiate it from Undertale's Flowey (not implemented in-game yet; condensed many of its facial expressions, need to refine and figure out some other ones.)

- Slight polish to the Crossbones "pretend" post-fight scene for better consistency with overall plans and design intentions (implemented in-game.)

- Chara now has armor sprites when grabbed by Koffin-K following the Mad House chase (these have not been implemented in-game just yet.)

And finally, we decided to give Muffet a dialogue SFX! Since she has a good deal of in-game content featuring her (i.e. battle, shop, hangout), we felt it made sense to add this detail which set her aside from other minor characters.

Team Switched @teamswitched.dev · 11/04/2025

New battle buttons! These were made by LuneyToons, with the exception of a brand new button variant made by Chip Potato -- when the player has run out of ITEMs, this will be reflected in-battle with an empty bag icon. Nothing major here, just little added details!

Harry and Larry's re-styled battle sprites are almost finished! There's just a few more we need to do -- to learn more, read the full section from this devlog (pictured below.) This has been a massive collaborative effort, and we're looking forward to getting this into players' hands!

An animated GIF of Larry from TS!UNDERSWAP, laughing. These new sprites were made by LuneyToons.

As we've mentioned before, the new battle sprites for Harry and Larry are almost fully finished! To put this in perspective: we've made 23 dialogue portraits (with 7 new ones), 26 battle heads (with 3 new unused ones), and 56 battle sprites (including new variants depending on the route.) Most of the work is due to how many sprites were reliant on the ones which needed the most changes -- and so when the "base sprites" were redone, we needed to redo or heavily modify all sprites which relied on the look and posing of them. All that's left now are:
- Harry's swipe attack (3 sprites)
- Harry laughing (2 sprites)
- Harry and Larry reacting to hitting each other (1 for Harry, 2 for Larry)
- Harry reacting to a shove forward (2 sprites)
- Harry and Larry's "fight cloud" animation (unsure right now, we plan to make an entirely new animation for this one instead of making it code-based.)

This has probably been one of the biggest collaborative efforts for a specific task with this project thus far, combining the efforts of Devilredd, LuneyToons (who made Larry's laughing animation above), Chip Potato, DepressoKnows, Beethovenus, SuperKirbylover, and EllisBros to get these done. We're not even finished implementing all of them in-game yet, either!

We previously mentioned how these changes were being targeted for the eventual Demo v3.0 release, given the following:

The amount of changes and fixes to existing content in-game (i.e. positioning, animations) will need testing to make sure there are no bugs created as a result, especially those which may impact other aspects of the game in unexpected ways.

The development branches for v2.0 and v3.0 are separate, as they use different versions of GameMaker, and so the changes would need to be applied across both branches and tested accordingly.

However, because we want to get these into the hands of our players sooner than later -- since Demo v3.0 is nowhere near complete, and will take a good while to get done -- we're hoping to re-target these changes for a Demo v2.0 update, but we cannot promise this nor give an estimation on when this will occur. Thank you again for your patience with this, and we'll make sure to keep you all updated!

As part of the last changes, we've also made a new sprite for the Temmie plush in Asgore's house -- this one was made by DepressoKnows.

Next, Temmie! They received a complete overhaul to their battle and overworld sprites -- maintaining stylistic consistency with the other Temmies' sprites, and the way our visual style has progressed as a whole. These were made by Beethovenus, DepressoKnows, and LuneyToons!

Want a quicker look at everything? No problem! 🧵⏬ First up were Papyrus's dialogue portraits and battle heads, which were modified to retain his angular look from Undertale. We showed these off here before, but here's a new GIF version! These edits were done by DepressoKnows.

Thank you so much to everyone who's enjoyed this project, and stuck around for so long! We hope you all have Happy Holidays, and a very Happy New Year!

Our official translations for Spanish (Español), Brazilian Portuguese (Português Brasileiro), and Dutch (Nederlands) are still in-progress, and will ideally be released whenever they're ready. (These are done by hobbyist translators, so please be patient!)

We're also in the process of discussing avenues for which community-created localization patches could be officially added to the game, including a list of guidelines (i.e. submission requirements, quality standards, etc.) It'll take us a bit to iron this out, so please give us time!

In case you haven't seen, we're now using Bluesky! This will be one of our primary avenues of communication going forward (rather than Twitter.) We've also been a bit more communicative in our Discord server this year -- including a new Community Spotlight channel we've made for easily shouting out fanworks! Feel free to join if you want!

Thanks for tuning in, and we'll see you guys next year!

Since the End of Year Q&A and Community Spotlight are pretty lengthy, we won't be including them here -- please make sure to check them out by using the GameJolt link! We concluded everything with "A Year in Review," discussing how 2024 has been and looking forward to 2025.

A Year in Review

2024 is nearly over, how about that? It's no big secret that this year hasn't exactly been the kindest to everyone, ourselves included.

We released Demo v2.0 at the start of the year, and we were really excited for people to finally see and experience what we'd been working on! To this day, we're incredibly fortunate and blown away by the overwhelmingly positive response to our little project, and the ways in which it's impacted others despite being unfinished.

Following this release, though, we unfortunately ended up having multiple stressful situations which, while thankfully resolved, definitely took their toll on us. Combine that with a slew of responsibilities and such in our personal lives which have required our full attention, and... in-game development has admittedly been much slower than we hoped following v2.0's release.

While various roadblocks have presented themselves, resulting in less work being done in-game, we've fortunately been making a lot of headway in other areas.

We've focused a great deal on properly fleshing out the game's overall outline, narrative, events, locations, and so on -- improving upon aspects which weren't as developed as we liked or needed, and even making changes to existing ideas to better suit our goals and direction for the project. All of this will significantly help us in the long term, and allow us to get future work done quicker by having a better understanding of what we want to accomplish!

While this project is going to take us a while to finish, we'd like to see it through to completion -- ideally sooner than later, mind you! Our work means a lot to us, and so has the support and kind words of everyone who enjoys what we're creating. We wouldn't be where we are without any of you, or without the hard work and contributions of each of our passionate team members. Thank you for believing in us, and for sticking around this long.

Here's to hoping for a better year with 2025!

We've showcased some preview screenshots of the Crystal Mines, the first sub-area of Crystal Springs! Since the area is still in relatively early stages, everything here is subject to change.

Obligatory Screenshots

Since Crystal Springs is still in relatively early stages, we haven't felt as if there's been enough progress to warrant showing much off -- though, it couldn't hurt to share some small previews!

Please keep in mind that all of these are entirely subject to change, and do not represent what they'll look like in the end. We've got a long way to go, including visual improvements!

We've been making significantly more progress with the Boogiemen's new battle sprites -- included are some examples of the work @thetoon.bsky.social has been doing for us here! We're close to wrapping up work on these assets, and we're starting the process of importing them in-game.

Gilded Goons, Again!

There's an image of Harry and Larry's new battle sprites in-game, standing within Koffin-K's study.

Many of the new (see below) re-styled Boogiemen battle sprites are courtesy of LuneyToons, our newest team member! They've been a huge help with getting these done, drawing inspiration from cartoon characters for some expressive animations and dynamic poses.

New battle sprites for the Boogiemen:
- Harry and Larry's hurt sprites (Harry smacked across the face with a tooth flying out of his mouth, Larry punched from the bottom of his chin with his face comically smashed upwards.)
- Larry preparing to throw Harry for an attack, holding him like a football. There is a variant for their Ruthless battle, where both look scared.
- Harry and Larry's "fish food" attack sprites. Harry is shaking a box of fish food, while Larry has his mouth wide open with a fork, knife, and bib.

The process behind these resprites has been a huge collaborative effort! As a rundown:
- Devilredd is responsible for the Boogiemen's new style (angular Harry, rounder Larry.)
- Harry and Larry's dialogue portraits were made by Devilredd (with input and edits by Chip Potato, Depresso, and Beethovenus.)
- Harry's default battle sprite was made by Devilredd (with some edits by Depresso.)
- Harry's battle expressions were made by Devilredd, SuperKirbylover, and EllisBros (with input and edits by Beethovenus.)
- Larry's default battle sprite was made by SuperKirbylover.
- Larry's battle expressions were made by SuperKirbylover, EllisBros, and LuneyToons (with some input and edits by Devilredd, Chip Potato, and Beethovenus.)
- Harry and Larry's hurt sprites, downed sprites, attack sprites, and scene-specific sprites were made by LuneyToons (with some edits by Beethovenus and input from Chip Potato and Devilredd.)

PHEW! I hope I got everything right there. Suffice to say, pretty much everything with this project has that level of in-depth collaboration between team members -- even to the smallest edits.

We're now going through the process of importing these assets in-game, and seeing how much we'll need to adjust and fix (i.e. positioning, animations.) Given the amount of changes present, it may not be feasible for us to apply these changes to both the v3.0 and v2.0 branches individually (since they're on different versions of GameMaker) -- we'd likely end up including these along with Demo v3.0 as a result, rather than having a v2.0 patch, but only time will tell.

Next up, progress updates! The main bulk of our work has centered around making refinements to both character backstories and route plans, as well as proposing potential rewrites of Ruined Home content for down the line -- though we've also made progress with art, music, and programming!

Progress Updates

Our priorities have more or less remained the same since September, and we've continued working on a lot of the same content when we have the time to do so.

Here's what we've gotten done:

- Writing -- More development on fleshing out & improving certain character backstories, evaluating plans for certain routes to keep them within reasonable scope, and proposing potential rewrites of Ruined Home content for better consistency with current plans.

- Art -- Some completed battle assets and concept art for Crystal Springs enemies, and the Boogiemen's re-styled battle sprites are almost completely finished!

- Music -- Some further work on "Boogie Beatdown" ("Let's Boogie!" v3) and "Kountdown" v3, with an almost-finished Crystal Springs track ("Dreamer" by philiplol.)

- Programming -- Work on implementing new Boogiemen battle sprites, Crystal Mines puzzles and area design, slight polish to Starlight Isles content, minor improvements to a few Ruined Home puzzles, and some Spep Mode work on the side. Also, updating the project to the latest GameMaker version and figuring out what breaks!

The three signs each have a unique icon above them (from left to right: a sun, crescent moon, and cloud.) The flavor text reads, "The CLOUD always lies."

We've decided to give this puzzle a little more flavor, with icon indicators!

There are four switches, each with a numbered floor tile underneath them (from left to right: 1, 2, 3, 4.) The flavor text reads, "From left to right..."

Certain puzzles with an order of switches now use numbered tiles as an added indicator.

First and foremost, we gave a recap about the contents of our September 2024 Progress Report, including our then-priorities and progress, as well as the release of Demo v2.0.7.

Hey there!

Today marks the fourth anniversary of Demo v1.0's release! To commemorate this occasion, as well as to continue our yearly tradition since 2022, we're sharing a new Dev Update.

As per usual, we'll start this one off by recapping our last progress report, and then get into our current progress updates -- along with some small content previews! After that, we have:
- End of Year Q&A
- Community Spotlight - Dec 2024
- A Year in Review
- Conclusion

Brief Catch-Up!

In our September 2024 Progress Report, we discussed our major focuses on making improvements to our workflow and further refining our plans for the whole game. Along with our general progress on asset creation and implementation, this included:
- Improvements to the game's outline (routes, endings, per-area content & bosses.)
- Refined character backstories for Alphys and Undyne, and review of others' (i.e. Ser Scratch) for potential improvements.
- Identified potential improvements to existing content for consistency with later material.
- Outlining and structuring work for Crystal Springs writing.
- Creation of re-styled Boogiemen sprites (complete portraits & default battle poses, other battle sprites in-progress.)
- 10 completed music tracks for Crystal Springs (18 in-progress, 14 planned.)
- 15 in-progress music tracks for Boreal Bluffs, and 2 remake tracks in-progress for Starlight Isles ("Let's Boogie!" v3 and "Kountdown" v3)
- Refined gameplay mechanics for the Crystal Mines (incl. set of introductory puzzles.)

We also showcased our current iterations of the Boogiemen's new default battle pose sprites, and a new Crystal Springs music track -- "Benevolent Interrogation" by DashingToadie!

Along with all of this, we also released Demo v2.0.7 with a slew of additions, changes, and fixes for localization tools. In retrospect, that was a lot we covered then!

Did you know: around this time last year, The Greasers were involved in an Undertale OC contest! To advocate for them, we posted these increasingly awful images. Enjoy the memories!

The Greasers with poorly-added red eyes. The text reads "humain... ;) We are remember you're ruthless Routes ; )" with the final two words in glowing red text.

Much like the image from before, but Aaxel is now preparing to punch Bugerpant, who is crying. With blood on his fist, Aaxel says "WE ARE GOING TO DUST TALE BOGAR PANT HUMAIN ;) IN THIS WORLD ITS KILL OR BE DIE......"
Crossbone is also there. He says, "human... i am cross bone"

It's much worse now. Norman has gotten wider, and has his face blacked out with analog horror eyes. Moldrick is purple. Gaster is behind Aaxel and Bugerpant, controlling them with strings like puppets. Crossbone is now visually distorted, with a bulge effect over his face, and the text "cross bone" has been blurred out.
A small Koffin-K is in the bottom corner, holding a megaphone. He says, "Wh... where am I?! BOOGIEMEN! I command you to help me escape this... this PUTRID prison!!! PLEASE...!" (They cannot hear him.)
