Built under the Bounded Agent Harness. The split edition underneath was written by four free models and combined by a fifth; this edition keeps that build and adds the playtest fixes (loop trigger, starting speed, vault spring, boss retreat) plus a whole second level — an elevator, a fireball powerup, and a locked-screen boss — carried out from the iteration prompt published on the walkthrough. Play the earlier editions: the split edition · the original · the split workflow.
One raw prompt in. A whole game out. See exactly how it was made →
You are Bit, a little agent bot. Run, roll, and jump through the Prompt Hills. Collect the ★ stars, stomp the glitch bugs, find the two secrets, and shut down the rogue Unbounded Core at the end.
Easy on purpose: 5 hearts, checkpoints everywhere, and a fall never costs you the run.
The tricks, honestly: three-plus layers of parallax scrolling, a tile-based level, momentum running, a rolling spin move, springs, a loop-the-loop, and sprites drawn entirely in code. The music is an original chiptune loop synthesized live with WebAudio — there are no audio files and no image files in this game at all.
