Excellent game, even with the difficulty.
I've noticed everyone complaining about the extreme amount of difficulty of the AI. And i can agree, it's a tough game, but it makes it much more interesting. It would be a lot less fun if you just sailed through each level without a scratch. You're going to lose a LOT more times, but that makes winning all the sweeter. Sure there's going to be a few levels that make you rage quit, but it's not impossible. This game needs skill, and a lot of luck.
My suggestions would be a little bit more health, to make the fights more worth while and entertaining, or perhaps more health pick ups. I timed some of my deaths, one only took 4.7 seconds. Granted i was in between two red barrels, but again, sometimes you get lucky, or a lot of bad luck.
Awesome game, looking forward to modifications and or a sequel!
