prasenx · x · 2026-11-15
Developer prasenx released Summer Festival, a free browser game built with Claude Code and Blender, calling it the coziest game he's played — made with Claude Opus 5.5 and Fable 5.2.
Set on the night of a seaside town's summer festival, you wander food and game stalls in a yukata. Completing five tasks — goldfish scooping, candy apple, ring toss, mask picking, lantern lighting — triggers fireworks over the sea. No score, no timer, no way to fail.
Key details:
- Runs on WebGPU, best in Chrome/Edge on a desktop GPU
- WASD movement, E to interact, plus wave/bow/cheer/photo emotes
- One-click switching between morning, day, sunset and night
- Townsfolk chat, stall keepers call out, a dog follows you, three cats hide somewhere
