Really love the art and animation on this one! The music was good, and the SFX work. I'm not a huge beat-em-up player, but I did enjoy the Scott Pilgrim game. This one gives me some of those vibes! I did however find the boss frustrating... the basic enemies are easy, but then the boss shows up and wrecks me in no time flat. I couldn't figure out how to hit it, and gave up after a few playthroughs.
Still, even if I couldn't beat it, I do think this is a good game! It'd be cool if you made this a longer, more complete game! Nice work! :)
