About ONOFF
ONOFF is a precise little platformer with a twist: the world is split into light and dark, and only one of them is solid at a time. Flip between them mid-jump to cross gaps, dodge spikes and reach the star in 25 hand-made levels.
How to play
Move with ← → or A D, jump with ↑ or W, and press Space to switch between light and dark. On touch screens use the on-screen buttons. Reach the star to finish a level.
