ONOFF is a fast-paced, hand-crafted platformer by Daniel Marino and Brad Dunbar, made for the js13kGames 2018 competition. Its 25 brain-teasing levels are built around one idea: with a single key you switch between a light and a dark dimension, and blocks and spikes appear or vanish with it.

Dodge spikes, jump over pits and time your switches to reach the star at the end of each level. The clean black-and-white look, its own music and a level editor for your own levels make it a great quick challenge.
