Added a lightning effect to the tesla turrets. Could be tweaked some more, but I'm happy with how its coming out!

So what is my game jam game? Its a tower defense where you, a giantess alien, are invading earth. Bwomf your enemies to immobility, and abduct them to grow yourself. Most visuals here are placeholders/WIP and either have been, or are scheduled to be, replaced.

Just got first set of lines from the lead VA for the game jam project. Will be exciting to announce *who* soon 😃

Game jam game is in that awkward spot where we're halfway through the jam and every day you question "do we have half a game?" I have the core mechanics working, art is coming in, and am starting to implement sound and polish - but still so much to do!

Bsky really doesn't like it when you make 200x200 images. Decides to blow them up and artifact them big time 🫠

How the gamejam is going

The artists have been making bangers of concept art. I also greyboxed some visuals for levels based off the art. Goal today is to add win/lose condition for a level

Made a lot of progress on my game for #SizeCon game jam over last couple days. Most of the foundations are in now. Goal has been to bang out the gamelogic side ASAP with WIP art. Then, spend rest of jam implementing the technical side of art assets

CrypticExpansion 🔞 @crypticexpansion.bsky.social · 12/09/2026
Refocusing my work on cowgame to make a game for the #SizeCon game jam! ~And don't worry, its not being left behind! Already some of the stuff I've been doing for the jam will be able to be repurposed for cowgame, and also just had a bunch of art come in today for it!

Turns out I was using the ListView for my UI incorrectly, so wasn't benefitting from its features. Got it fixed, all lists now properly use it. Oops!

Amusing, unintended - but acceptable - behavior. I gave cows random band sizes, and then calculated a bra size based off of their volume + band size. For now I defined up to a V cup and when a girl hit *past* V cup, it just added a "+" at the end 👀

Met a goth girl the other day, got a date next week. I mentioned I'm working on an indie game, and she wants to know what it is. Gonna be a fun convo explaining I'm developing a hucow management game

WHAT THE HECK?! I am SO thankful to my amazing and generous community. WE HIT THE GOAL ON DAY 1! Total is at $5075 (after error adjustments) and I have over 156 HOURS on my clock to stream! There will be stretch goals announced soon, with all proceeds giving us better financial stability to move~

Budgeting out screen space for various UI windows. Unexciting but important work. With it I'll have a better idea on what kind of art assets can fit into the game, and where, as well as how granular I can get with the cowgirls!

Another friend joined the team on the cow game, he'll be helping with coding and possibly some blender support

Next goal is deepening cow system. There will be a recruitment pool for cows, where you can see their traits before hiring. Not all Cowpplicants will start lactating and ones that aren't will need time before they become productive members of your herd!

News ticker created. It plays two kinds of messages, event-driven messages that will play when the player does something noteworthy that should affect the city. If no event message is playing, randomly it will play filler news Gonna do more logic with it later, but its good enough for now

Back on NSFW gamedev again. Created a system so that characters can send messages for certain events, such as when research is completed. Messages que so they don't overwrite one another, dismiss after time delay or can be clicked to dismiss manually.

I ended up abandoning this project because my softbody wasn't playing nice with painting, another core feature of the game. Well, yesterday I got the two working together! :) Still focusing on the cow game, but that old game will be easier to revisit!

One thing that still gets me a lot in gamedev, is you'll meet someone who knows all sorts of amazing things that makes you think "wow, I know jack shit" Then later on they gush at your knowledge about a different aspect of gamedev that you know more about

Been playing a few tycoon / business management games recently to try and get more inspiration for mechanics on my HuCow game. Anyone have any recommendations?

Temporary menu for managing some of the cow stuff. Going to replace this later, but wanted to experiment with giving the cows different kinds of drugs. Also sent first (super early) alpha build out to some testers!

Got a research list prototyped. At some point I'll rework it later so it shows the bonuses you're getting from the tech too, but it'll do for now. Finishing up some research calculations, and then we're onto the Cows!

CrypticExpansion 🔞 @crypticexpansion.bsky.social · 01/05/2026
Worked on adding research to my HuCow game. Research list populates and considers prerequesite projects progress, you can click on each one to start researching something. Also reworked my Research Tool to allow for adding a Research Unlock vs Bonus. Still working on making tech do stuff though!

CrypticExpansion 🔞 @crypticexpansion.bsky.social · 28/04/2026
Progress over last couple days on the HuCow management game. You can now accept contracts, and fulfill them. Contracts also go in a list. Basic gameplay loop done, sans economy, working on Research system next. After that I'll figure out what to do with the HuCows. All Visuals are WIP

Markers now properly are set based on building height :D They normally won't be this jampacked, just testing atm

I have an artist for my game now! Had a great convo with him where he sketched out the idea while I described it. Seeing a visual idea-board makes it feel much more real and exciting than just writing ideas down. Should have a little prototype in the next week or so!

"Out of control breast expansion is actually a far more common problem in the multiverse than most imagine, but fortunately, space is the final brassiere!" Yup, I upload my "Mer-May" piece on the very last day of the month so I can have the last word on the subject, and that word is BWEBS! ^^;

お星様からたくさんエネルギーを受け、 淡ちゃんは更に成長しました 本人はもう満足していますが…大宇宙先輩はどうかな?🙃 最終段階の集計は5/16(金)です! Awai received a ton of energy from the stars and ended up huger. She is now quite satisfied with the results, but...is the universe? 🙃 Reactions for this final phase will be counted on EOD May 16th! #超乳 #膨乳 #growthdrive
咲-Saki-からの大星淡です。
第二段階の成長促進の結果を用いて身長が12m弱、
おっぱいが6000cm弱、お尻が5mくらいになりました。
いやぁ、校庭を多く占めるデカパイに学校の四階にある部室に手を入れて麻雀をしてる淡ちゃん、絶景ですね。
それでは更に成長させていきますので、皆様たくさんの反応をよろしくお願いします!
集計は5/16の終日ですからね!

Awai Oohoshi from Saki.
From the results of the second phase, she ends up growing to a little shorter than 12m in height, a bust close to 60m, and booty of 5m.
A wonderful sight to see with her breasts covering a wide area of the schoolgrounds and her reaching into the clubroom on the fourth floor to play Mahjong.
Well, the growth will continue this time, so hope to see many reactions to help that out!
Reactions will be counted on May 16th, your EOD!

淡ちゃん、星と話してから数日で急激に成長しましたが、まだ足りないみたいです フェーズ2は5/4(日)終日で集計しますので良ければそれまでにご反応ください! Awai went through a sudden growth spurt for a few days after speaking to the stars, but she seems unsatisfied. Reactions for phase two will be counted on EOD May 4th, so keep that in mind! #超乳 #膨乳 #growthdrive

前回の成長企画第1段階で大量成長しまして、公園も狭く見えるくらいの身長とおっぱいになりました
さて、次の成長期ではどれくらいデカくなるのでしょうかね
よろしくです

Awai Oohoshi from Saki.
So, from the last growth drive phase, she gained a lot of height and boob size to make even a park look cramped.
Time to see how much more will be growing in this phase.
I am counting on you all.
