I sorted out my problems with duplicateMovieClip, and I have great news; the demo now allows you to spawn as many enemies as you'd like! The game tends to slow down when you decapitate six or so dudes at once, but I think it looks kinda cool. Think of it as slow-motion for your big kills! However, a kill of 20 or so may cause extreme slow down, but don't bitch 'cause when you're not in control of the spawning like you are in this demo, I won't spawn that many on you at once.

UPDATE (9-3-08): If two or more enemies are on screen at once, they should now stand at two different places (10 pixels apart) to show that there is more than one enemy at that spot.

Play my latest progress here, and please leave a comment with some feedback for me!

Slice several dudes in half at once!
