Thats a nice concept and i like the visuals,
your sprites while having a simple ball shape have a lot of little details to give them character, and the sword has a cool design as well :D
Also gotta say that the story is cool and that the wordplay with the title is as well, and quite clever ^^
The difficulty and balance seems to be the biggest issues i encountered, cause even though i like the melee concept and the fact that you let attacks have a separate orientation from where you're moving, i still think it's a bit hard to navigate the patterns to come close enough for hits especially with the time pressure, but considering the jam's time i can totally understand that you probably didn't have the time to find the right balance. nothing a bit of tweaking can't fix, cause there's an interesting base.
Other than that, still a nice experience so well done to you guys :)
