A WEBGPU CAT PUZZLE GAME SHIPPED IN THREE DAYS ON EXPO, WITH AN AI AGENT AS THE QA TEAM

Summary from the TLDR Dev newsletter

Purrkour went from first commit to App Store-ready in three days using a shared TypeScript engine, Expo, and TypeGPU, with procedural graphics and audio. A solver verifies the puzzles, while an AI agent tests actual gameplay through Argent using a debug bridge that exposes board state and exact tap coordinates.
