-We gettin' freaky on a Friday Night, yeah!- Press F to toggle filter. Click Options for options. (duh) WASD/arrow keys/touch screen are controls space/click to restart when you die (other keys take you back) left/A and right/D to change difficulty settings on the menu (sorry mobile users) It's basically like DDR, press arrow when arrow over other arrow. And uhhh don't die.
This is the REAL Friday Night Funkin'.
