Good start!
This was a very good start, this is a great timewaster. Oh, Darth Draconis, you're a total jackass. You havn't done any flash, so you have no idea how hard it is. I know, I havn't submitted any flashes, but I've tried making flash, and it's hella hard.
Back to the review. Pretty good timewaster, but you need sounds and a scoreboard. Maybe some different enemies. And also, different levels. When you hit an enemy, you don't really know you killed it, all it does is teleport away. You need something to show that you've killed the beastie.
Hope this helps!
