Agree with the dev below, this looks so refreshing! All the lighting is really well implemented.
I think a small tweak to make to the game is the control scheme - I know it's because of 3D movement being a bit harder to implement, but the fact that your aim is tied to your model rotation makes it difficult to aim well without getting motion sick, and you need a large distance to turn fully, which means that in the first arena, for example, it's hard to kite the enemies around effectively without taking damage. Either that, or reducing snowball cooldown to get more hits in before having to turn again, would be nice.
Other than that, love the dungeon crawler-esque gameplay!
