Use the arrow keys to move around and avoid EVERYTHING! New enemies will keep appearing, and you've gotta dodge them all. You do get a health bar for 3 hits to keep from dying too fast at least... How long will you survive? Can you go a full 90 seconds???
This game was created for the Experimental Gameplay Feb 2011 challenge: ASCII. I actually made it in 6 hours! If it gets any kind of plays at all, or you see even a glimmer of fun in it, I'm planning a much better version (to fulfill the whole one-week challenge to Experimental Gameplay), where you can return fire, fight multiple enemies, play with multiple difficulties (bigger versions of Squareface) and the like. It'd be called ASCIIvader 2: Revenge is a Dish Best Served Square.
