Use the arrow keys or WASD to move and avoid the obstacles (enemies)! Press down to fire lasers! There will also be a bonus level at the end of each stage if you finish in over a certain amount of seconds. After every level you get a code so that in the beginning you can type your code or say no code if you're just starting and the code will take you to the level the code belongs to. There is no code for the first level.
