Before playing the game it is recomended that you change the control scheme. THe default control scheme is the up bittuon is yp amd down is swallow, left amd right buttons move you in that direction. The Alt button allows you to absorb enemies, use their ability, puff out excess air, and shoot stuff, space flies you. If you don't change the control scheme the alt button will cause weird things to pop up when cobined with directions. I recommend changing the absorb to shift, to do that go to the controls after the scene.
