This was a super satisfying and fun game! The mace-like mechanic for combat makes for some really fun physics, and you've got some excellent game juice going as well. You used plenty of screen shake and particles, which really adds to the game's polish. The movement is snappy, and the models and textures look really good and fit the game's aesthetic.
Some things I would like to point out is that if I defeat a wave much earlier than anticipated, then I'd have to wait until the bar goes down before I fight the next wave; gameplay would be much smoother if you make so it immediately transitions to the next round if you kill the wave before the bar goes down. It would also be nice for the beginning enemies to have at least two hitpoints, mainly because I think it would be funny to add insane knockback with the ball and chain. There also seems to be a slight bug where the camera slightly shifts when the screen shakes.
Overall I really like how this one plays! Hope this one does well!
