Welcome to Blockjaw: the Falling Blocks puzzle game you play with your face. (° _ •)
Move the pieces by shifting your mouth left and right, rotate them by blinking, increase fall speed by opening your mouth, and drop them all the way by sticking out your tongue.* Fill entire rows in order to clear them, but be careful because the speed slowly increases as you play. Keep an eye out for future game modes!
(*Game requires a device with facial-recognizing AR capabilities. An alternative AR version of the game will still be playable on devices without facial AR, with limited functionality.)
