The full story
PolyRoll is a 3D marble game for phones and desktop inspired by Super Monkey Ball and Marble Blast, built with three.js and cannon-es physics. The author had never tried agentic coding until a friend showed them Claude Code. After planning with Gemini, Claude Sonnet produced a buggy but working game in an hour or two. More prompts then fixed bugs, tuned the feel and camera, and added a touch D-pad designed from a photo of a mock-up.
