You and your companion can only move when in sync with the rhythm but don't worry, the polygons only move then too! The game is couch (more like keyboard friendly) co-op!
Controls: W, A, S, D for left player and either I, J, K, L or arrow keys for the right player. Watch out though, because your inputs need to be timed to the beat!
Just a heads up that the game crashes at the end of the last level... and you can't die. Woops. But do play until the end, the music is great and let me know what you think!
