Iterplay turns a design doc into a browser game (for now, a single-level 2D platformer), then improves it automatically. Gemini writes the game, bots play it while being recorded, Gemini critiques the footage against the design doc, a deterministic verifier checks every claim against telemetry, and the fixer patches the code. The loop repeats until the game meets its rubric.
