Nice and well polished game. The AI was a pretty good challenge and felt decently smart. The music remixes were really good too. The fact that you could pit the AI against itself is a great addition. At one point I pit 2 AI Cirnos against each other, and they both made the exact same decisions and ended up knocking each other out, ending the match in a draw. One thing I would say is that I feel like characters should have more health in general. I found the best strategy was to just go in and hurl snowballs at the opponent until I won, since they'd run out of health so quickly. Matches should go on long enough that I'd feel more compelled to set up a base, plan attacks, etc. Otherwise, really good job!
