Honestly, I got frustrated after a couple levels because it took so long to get to the point I was at in a level then I got stuck and was forced to die so I gave up. This goes back to the movement mechanic being very slow and having annoying collision detection.

Yeah, I'll be working on that for the next few weeks :) but I'm not updating anything till voting is over (not even movement speed). I have a long list of things to fix and I can't wait to upload an updated version where all those things are fixed ^_^
Level 2 is probably the worst as far as design goes. 3 and 4 are a lot shorter and 4 has a gun ^_^
