You may have guessed it from my submission but I'm a sucker for beat-em-ups. I loved this! It was so solid! I was challenged, I was intrigued; the music and graphics and sounds all worked well and supported the idea. I also never felt like I should have hit something when I didn't, or that I was punished unfairly. I'd love to see this made into a full game. Like others said, it'd be a shame not to have more enemies to absorb/transform into. (Probably that was planned but I know how jams are :P)
Awesome job!
