No. The game runs directly in your web browser on a custom WebGL engine. There is nothing to download and no plugin to install; it works in Chrome, Safari, Firefox and Edge.

On desktop you hold A/D or the left and right arrow keys to steer. On a phone or tablet you drag anywhere on the track, or hold the on-screen left and right buttons. The prism rolls forward automatically — you only steer sideways.

Your score is the distance you travel before crashing. The prism speeds up the further you get, so higher scores come from surviving longer at faster speeds. Your best distance is saved on your device.

Power-ups you pick up during a run are temporary: a shield absorbs one hit, a magnet pulls in energy, a slow field slows time, and ×2 doubles energy collected. The energy you bank is spent in the Garage on permanent upgrades that carry across every future run.
