FishSlop is a browser game where you pilot a tiny submarine through richly animated underwater tanks — feeding fish, grabbing coins, blasting aliens, and buying egg pieces to unlock the next level. The title screen alone shows off gorgeous 3D-rendered sea life, sandy floors, and volumetric lighting. Theo's Claude Opus 5.5 run produced the best version yet: fluid controls, a complete gameplay loop, a functional in-game economy, and four distinct named tanks from Kelp Hollow to The Abyss.

Best animation and controls Theo has seen across all AI-generated versions of the game

“Opus 5.5 had the best run with FishSlop that I've ever seen. The animation quality is incredible. The controls feel so much better than any other version I've generated. There's even a complete gameplay loop with a functional in-game economy and unlocks.”
