This is probably one of the most creative interpretations of the theme in this jam, and so it immediately stood out to a lot of people as having potential, which is awesome! I'm not sure if this genre fusion exists, so understandably you'd have to work out many design choices on your own, and you did a pretty good job. Both the fighting and rhythm game aspects are as expected, but the interesting part is transitioning after you hit a fighting game health threshold, and having both the rhythm game and mash section impact the health as well. A lot of strategy/appeal could come from making this transition logic more complex - so that players would be kept on their toes by constantly juggling the 3 different modes and switching between them, being sure not to do the wrong keystrokes at the wrong time - and timing transitions to mess someone else up as well. The base gameplay as presented is definitely a little sluggish just because it was made so quickly and probably didn't have time to get balanced with appropriate timers/iframes. But again, with more exploration of the mechanics, this could be a really interesting game with a high skill ceiling.
