It is a good package!
Animations and art are cool, and I like how all attacks really pack a punch.
The difficulty curve is probably a bit off though. I don't think the general difficulty of the game is too much (it is meant to be brutal) but I feel the curve should start way lower at the start - especially for a jam game. Many players are going to be discouraged right at the start.
The way camera rotates makes me slightly nauseous. It also often ends up in angles where there are enemies coming from behind the camera. I would prefer the camera be a bit further away and rotate way less.
Overall, a very solid jam entry with some spots for improvement.
