Nice. Making an arena game like this fit's the theme pretty well and makes for an excellent highscore game.
(I just barely broke into the top5 at place number 5)
The graphical style reminds me of the art of Slay The Spire, which I liked.
The combat felt a bit unprecise at times, like some of the directional forces lingered and still moved the characters while the graphics were already gone. Especially when creating a big balloon and having some enemies around the resulting physics can become pretty unpredictable. Sometimes you can just move around and it's fine and sometimes it will shoot you off the platform.
Also the amount of graphical assets needs some calling out. Well done.
