Quite a fun game!
Obviously it is a bit of Vampire Survivors clone, but I really liked the idea and story plus the abilities of our mon. It feels fun to play and is polished for a jam game. I played it until the very end, and the only moments I was struggling was around 2 minutes and then 10 minutes :d It was getting a little bit overwhelming there, while it was easy in other moments. But nevertheless I enjoyed it. A couple issues I had was that with all exp and our abilities being this neon yellow, it was hard to see at times. I think the XP sprite colour could be a bit toned down and maybe made a little bit transparent as a couple of times I almost didn't notice the enemy under huge pile of xp and they hit me. And personally while the sound effects are nice, when I was picking big piles of XP the sounds did get a bit annoying. Obviously it wasn't a big issue but definitely noticeable for me.
Overall a solid entry that is very much fun to play. Good job!
