Two levels that repeat forever. Each time you beat a level you 'go down a floor', or play another round. They're the same thing. Move with the arrow keys, shoot with space. Avoid the dashes, they'll kill you. The only external code I used was the Timer code provided by PoV and the cursor moving code, provided by the internetz. I used an ASCII art generator for the Game Over text, it's the first result on Google.
