First of all, IF YOU DO NOT HAVE A MICROPHONE YOU CANNOT PLAY THIS GAME! If you do however: Press the A key and slide your finger in a straight line all the way to the L key, then tap your screen! This is based off of the Iron man infinity war effect (the way he puts his suit on).
Michael Codney (for telling me how it works). My sisters, and my cousins for beta testing this.
