Arrow keys to move & if you lose all your lives the platformer restarts. You can spend gems at the shop to get more hearts or fly for one level. If your score is high enough you will automatically fly, in level 6 you automatically fly to show you how it works. Don't touch acid or lava or you lose a life. In the duel, 0 or press the alien for shield and space or press anywhere for an arrow.
