I really like the spin mechanic here. Takes a little bit to get used to but it feels good after some practive. My main critique for your game would be to let the player retry bosses after they die. In a normal game I get that this is a roguelite and you should go back to the start and spin the wheel to get different items. But for a jam game generally you just want people to go through your game without hiccups so they get to the end.
Overall I liked it though. The telegraphing on the first boss was really good. I didn't quite understand some of the mage bosses mechanics which is probably why I died twice to it lol.
