You are a sine wave

Experience an experimental game where you control a sine wave's frequency and amplitude to avoid obstacles and collect squares to increase your score.

Zone out

The better you do, the more colorful the game becomes, and the more instruments join in the song. 

You can also try Zen Mode, and just relax while you play with fewer things to focus on.


For those with epilepsy, or who experience eye strain or motion sickness, there are adjustable settings to make the game as accessible as possible.
