Nice beat-em-up with a pretty good amount of polish for a game jam game. I feel like everything comes together pretty well and I especially liked the music and voice lines. The art-style is visually pleasing and I enjoyed the fact that you ran through a variety of backgrounds before reaching the end.
The actually gameplay felt pretty nice as well, a little repetitive, though I feel like it would be hard to add more variety in a 7-day timeframe. Certain enemy attacks would be hard to predict/bait out, but overall I'd say the game felt pretty good.
Also, if I'm correct and there are i-frames when you jump, I feel like that is a really nice touch (the final fight became easier when I figured that out).
