Added a score system! This is the first step toward Unityroom high-score rankings. Ranking support isn't there yet, but it's planned. (It's mainly for the Japanese market, but Unityroom's score ranking feature is really nice.) #GameDev #IndieGameDev #GodotEngine #solodev

After 1 year and 2 months, the game is complete! Now I’m doing browser-specific debugging. WebGL (GLES) has lots of performance limits, so it’s been a real challenge. Hoping to release in 1–2 weeks. #GameDev #solodev

I created a language selection screen that appears at startup, along with instructions for key assigns. As for explaining the controller, I still haven’t found a good solution to the issue that the layout differs between Switch/Xbox.🤔 #GameDev #IndieGameDev #GodotEngine #solodev

I’ve been creating individual BGMs for each stage, and this week will be the last one. This track is for the underground stage. Starting next week, I’ll be adding images for the control instructions and doing some final tweaks! #GameDev #IndieGameDev #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 05/04/2026

This week I worked on the overworld Stage 2 track. I have this problem where making music makes me want to make a game, and making a game makes me want to compose music.🤔 Strangely enough, though, I’ve never once felt like drawing.😅 #GameDev #IndieGameDev #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 29/03/2026

The idea was to begin with an unsettling minor key, break through the old title screen,then lean a bit more into a major key before settling on the motif also used in Stage 1.Probably due to the short length,it doesnt quite reach the ideal I had in mind.🤔 #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 22/03/2026

Over the past week or two, I've been working on the opening cutscene. The last game only had a simple fade-in, so this is definitely an upgrade!😇 I'll be adding the sound next. #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 08/03/2026

This week, I composed a new track for the sky stage. The idea came from a simple chain of “sky → bright → Latin.” If I can finish two more songs, every stage will have its own track—so let’s keep going! #GameDev #IndieGameDev #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 01/03/2026

I'm writing dialogue for the characters. I’ve never written a script or dialogue before, so progress has been pretty slow, but I'm hoping to push through and get it done somehow!💪 #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 22/02/2026

I'm continuing the final adjustments, even though there aren't many visual changes. I also composed a new track and turned it into a video. It has a somewhat intense feel, so it might work as the final stage BGM? #GameDev #IndieGameDev #solodev

0113

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 15/02/2026

Still working on the final adjustments. I also tweaked the effects on the mode‑select screen. Maybe it could be a bit flashier. #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 08/02/2026

I'm creating the final stage. Also, since the music I had been using for the underground stage wasn't very good, I made a new track and replaced it. It's definitely better than before! #GameDev #IndieGameDev #solodev

0142

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 01/02/2026

I'm working on the final stage now, so there isn’t much I can show. This video is about a feature I added that can hide the HP/POW bars when they’re not needed. #GameDev #IndieGameDev #GodotEngine #solodev

This week, I created a time‑delay switch that works in conjunction with a shutter. It will be used as a puzzle‑like mechanism when combined with other parts. With this, the creation of the mechanisms is almost complete! #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 18/01/2026

There was feedback for a previous version saying that it was hard to tell whether something could be grabbed with the hook or not. So I’ve added a lock-on cursor. (Thanks for the feedback!) And some UI improvements, showing the forcedscroll direction,etc. #GameDev #IndieGameDev #GodotEngine #solodev

Let's keep working hard on game development this year! This week, I created the flow from clearing a stage to selecting the next stage and starting it! #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 23/12/2025

This is gonna be my last post of the year about game dev, maybe🤗 Last week, I was working on enemy objects for the minecart stage and adding the feature to switch ride between minecarts. Still feels it needs more polish to look good🤔 #GameDev #IndieGameDev #GodotEngine #solodev

I've started working on the middle part of Stage 3. When it comes to underground stages, mine carts are a must, right? Let's keep refining it and add some extra details. #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 07/12/2025

I bought SFC’s Soft Synth during the Black Friday sale! And remade Stage 1 with SFC vibes. The SFC sound is very bright and colorful, but it feels like it requires a lot of skill to master. I think I can make it even better. #GameDev #IndieGameDev #solodev

0143

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 30/11/2025

I've wrapped up the first half of Stage3 this week! Since it's pretty maze-like down there and visibility isn't great,I put signboards along the less distinctive paths to players find the way. Next, I'll start working on the middle section! #GameDev #IndieGameDev #GodotEngine #solodev

0184

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 23/11/2025

Working on creating underground enemies.Cause visibility around them is poor, they're not set to be very strong.It was quite challenging to make them adhere to the ground instead of being affected by gravity and also allow throwed by hook rope. #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 16/11/2025

I'm still working on some underground mechanics. I want to design a puzzle-style challenge, but it's proving pretty tough for me! #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 09/11/2025

I was down with a cold last week, so progress on game development hasn't been great. I've been spinning a strange machine located underground.😵‍ #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 26/10/2025

The background design for Stage 3 is almost complete.The lighting range (size) still needs some consideration.🤔 Next, I'll start creating and placing gimmicks and enemies. #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 19/10/2025

I've finished creating Stage 2, so I'm about to start working on Stage 3. This time, it’s going to be an underground level—a complete contrast to Stage 2. I’m aiming to wrap this stage up before the year’s over! #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 12/10/2025

Working on the Stage 2 boss again this week, so no major progress to share. I recently arranged the stage select theme I made earlier using a MegaDrive (YM2612) + effectors setup. With effectors applied, it might not sound very authentic… Compare with previous NES version repost. #GameDev #solodev

0161

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 05/10/2025

I've been working on the rest of Stage 2 this week. It's almost done, so next week I'll start making the boss. I started around mid-August, so I guess each stage takes me about two months.🔨 #GameDev #IndieGameDev #GodotEngine #solodev

I've been working on the second half of Stage 2 this week. It's still a WIP, but this part's tricky — lots of spots where you can fall if you're not careful. Trying to keep it fun while still challenging is always tough!🤔 #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 21/09/2025

I was out a lot this week, so honestly, there’s not much progress. I just worked a bit on the save data. Totally unrelated to game dev, but the photo is of a “bell” I found by the side of the road while I was out. It looks way too small to use in an emergency, so I have no idea what it is🤔

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 14/09/2025

Hop aboard a small airship and start shooting! You'll literally be using "buttons" to control it🎮. The enemy movements I made last week were a bit too difficult, so now a warning🚨 will appear before they shoot. #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 07/09/2025

This week, I was working on creating the mid-boss for Stage 2. It looks like fighting it with a sword will be tough. Next week, let's prepare a weapon to defeat it! #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 31/08/2025

This week, I created two enemy characters for the aerial stage. I had a bit of trouble that create using the hook rope to throw enemies that aren't affected by gravity. #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 24/08/2025

How about hanging onto a cannonball and soaring through the sky? It's not super exciting gameplay-wise, but it does help mix up the pacing — pretty neat. As an extra step, we’ll probably need to add enemies at the landing spot. #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 17/08/2025

This week, I worked on the background graphics for Stage2. The second stage is set in the sky, so it’s going to be an aerial battle. Next up, I’ll be building the level and adding some new enemies! #GameDev #IndieGameDev #GodotEngine #solodev

This week, I added a feature to the stage-clear sequence that displays a bonus based on the number of citizens rescued. I’ve liked "Metal Slug" does this, so I tried implementing something similar.I hope it gives off the right vibe. #GameDev #IndieGameDev #GodotEngine #solodev

I finally played "goodbye world", which had been sitting in my lib. forever. Absolutely loved it—the story was "pain" in the best way. Solo devs or small teams, you need to play this.🎮 store.steampowered.com/app/1833490/... "Kani-Chan" was so me—I actually thought, “Wait, is this my story?”🤣

Still working on the tutorial castle! Supporting both keyboard and game controllers is tricky-figuring out how to show the controls in-game isn't easy. Low-reso icons alone feel a bit unreliable, so I've added text explanations. #GameDev #IndieGameDev #GodotEngine #solodev

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 06/07/2025

This week, I created a new castle🏰stage along with a music track! The stage is part of the story and serves as a tutorial, so no enemies here. Next week, I’ll be adding some signboards with gameplay instructions to the background! #GameDev #IndieGameDev #GodotEngine #solodev

Shopping is finally working after this week’s updates. Not much has changed visually, so it’s kinda low-key… but,I struggled a lot because I was sloppy with managing variables and state😅 Note to self: Next time, no shortcuts—design it right! #GameDev #IndieGameDev #GodotEngine #solodev

0143

KatsuKarei(かつかれい) @katsukarei120.bsky.social · 15/06/2025

I'm continuing to work on the shop scene. The screen transitions and animations are mostly complete, and the sound has been added. Once the purchasing functionality is implemented, it will be nearly finished. #GameDev #IndieGameDev #GodotEngine #solodev

I'm feeling much better now, so I made a new track for the shop scene this week. Like before, it's built with the NES (2A03) + Effector setup. I’m planning to start building the shop scene over the next two weeks! #GameDev #IndieGameDev #solodev
