OpenCode's Space Bunny builds a self-tested HTML game and fixes its own two bugs

A user tried Space Bunny on the open-source coding agent OpenCode, asking for a small space game in one HTML file. The result, "Bunny Blast," draws everything in code with no image assets, supports arrow-key movement, space to boost, and a high score.

The standout: before handing it over, the agent playtested the game itself, found two bugs (asteroids spawning off-screen; the game-over screen never appearing), and fixed both.

Space Bunny is free on OpenCode for now. OpenCode supports terminal/IDE/desktop, 75+ LLM providers, has 208K GitHub stars and 16M monthly developers.
