Wow, this was a really cool little game!
My two complaints would be:
1. The hitbox you have seems a little buggy at points, with enemies damaging you from a fairly big distance and sometimes after they're dead.
2. The lack of a slide move for your character. I noticed the other characters doing cool slides to avoid enemies, left me feeling kind of envious that I couldn't do it too!
Otherwise, I really enjoyed the game and look forward to more!
