Awesome presentation. Love the intro, the writing, the tutorial... the post-apocalyptic color scheme, the lively animation.
Controls seem fluid and well-implemented, BUT I experienced what I believe to have been a very serious bug. After taking about 1/3 damage, I could no longer attack any enemies. Since defeating enemies is also the way to heal, I would basically get stuck whenever this happened. (If this was intentional, and there is some gameplay way to get out of that spiral, I was not smart enough to figure it out. :) )
