Hop up one-way platforms, leap the spikes and grab every coin to raise the flag in this cheerful pocket platformer.

Moon Hopper is a bite-sized night-time platformer built with the PixelJS engine. Four coins are scattered across floating platforms above a row of spikes; collect them all and a flag appears at the very top. Reach it to win.

Run with the arrow keys or A and D, and jump with the up arrow, W or Space. On a phone, use the on-screen buttons; gamepads work too. Platforms are one-way, so you can jump up through them from below and land on top.

Touching the spikes sends you back to the start, but the coins you already hold stay collected. Every sound and the little looping tune are synthesized by the engine as you play.
