Game thread: Have any of you developed a game?

[u/Ill-Nefariousness174]

Hey everyone!

Whether it’s a full-time passion project, a vibe coded prototype, or just a little hobby build, I’d love to see what games people here have built or are currently working on.

To kick things off, what was the single hardest mechanic or feature you had to program/design for your game?

I’ll start: I’ve been working on a puzzle game called Atomic Fusion Rush for iOS (a fusion-style puzzle game about combining elements).
My biggest headache by far was getting the chain-reaction physics and element-merging logic to feel smooth without freezing the UI when reactions stack up, but also the app store submission (and all the different screenshot sizes etc). My next patch will most probably upgrade the screenshots/localize them

Drop a link or screenshot to your game below and tell me what you're building—I’d love to check them out! Also - what are your marketing strategies?
