Bouncy Doggo

A golden retriever with springs for legs, bouncing up through a meadow, past a few mailmen who have not forgiven him, and out into space. He handles the bouncing. You steer, and you get one extra jump when you need it. It starts friendly. It does not stay friendly.

The whole game is one HTML file — physics, world generation, hand-drawn art, synthesised sound and save data in a single script, no build step — which is why the browser and the iPhone run a byte-identical build. Keeping it honest takes thirty test tools, one of which injects thirty-two known bugs to check that the other twenty-nine still catch them.
