How to Play

Your mission is to destroy each invading Frequons by moving the cursor on top of it. What could be easier? Except for one itty bitty detail: the Frequons are not displayed in the usual spatial domain, but in the Fourier Domain. Frequons look like colored waves. Your "self" is a wave too, with opposite polarity. Instead of manipulating some local point on the screen, you manipulate a global wave pattern. You destroy Frequons by achieving destructive interference with them.

Here's a screenshot of the Windows version:

The game comes with more documentation. There's a training mode for learning how to play by experimenting. So don't worry if you don't know what the Fourier Domain is. By playing it, you'll develop a feel for a game that has been described as psychedelic, compelling, and strangely addictive.
