Your game is easily one of the best in the Jam, or, at least, the one I played that most caters to my preferences.
In such little time you've put together a great combat system and an interesting and balanced assortment of enemies that work well together, so the game is challenging, fair and fun. I just found the timing wheel to be a bit hard to follow, it felt like there weren't enough frames to capture all its nuances, but I was still able to get the timing right for almost all of the enemies, except for the flea, that was a really hard one.
When I first ran the game, yesterday, it was extremely laggy. I don't know if it was a bug you patched up or something on my side. Also, first time playing it today I got the main menu music stuck, so I didn't hear any of the game soundtrack. Had to start over and hear them, but that bug was something browser side, I'd wager.
Everything you guys did here has excellence, the art, music and mechanics are all beautiful. Up until now, my favourite game in the Jam.
