You move your mouse over the blocks at the right time. ---- Make a custom song in the map maker. You have to edit the game to import your own song into it though.
This game was inspired by Beat Saber. -Important- I made this game a couple months ago, but I eventually just lost interest in developing it because of some bugs that I couldn't figure out. I hope you guys enjoy the game though, and I hope you continue it's legacy by making songs for this.
