For the final week I chose to play test and dial in my week 1 submission. USA-OS. I admit I had ambitious plans, but I side tracked myself on tooling.
In this update, I added more achievements, balanced out the game play, and really focused on some endgame things that I don’t want to give away (spoilers). Perhaps there’s a cheat code waiting to be discovered. Or unlock all the achievements yourself to see what new special thing happens now! It’s worth it, I promise!
The process:
Hereme’s + Codex
I developed a very nice process for local image generation but I’m still dialing that in. I may post about it later. For now I’m still using GPT 5.X for sprite generation.
stable-audio-3 for sound effects
