The spaceship is directed by the arrows for player 1 and wasd for player 2. Be sure not to touch a lemon or you will die and the lemons will take over again. Shift is turbo for player 2 and space is turbo for player 1. You can use it infinitely, but it will be easier to crash. never mind just don't die.
:) two player might be coming don't know if I will though
