Arrow keys or WAD to move, mouse to shoot. You can view more about the game by clicking the HELP. Scroll down to see the codes, and what they do. Hop2It, SKIP3, 4kLift, and 7UP all take you to the level the number is. BOSStime makes the levels only have the boss, but the boss is tougher than normal. PowerUPx4 gives you all of the power-ups.
