The mixed pixel sizes on all assets threw me off at first, that and the fact that none of your assets are constrained to the pixel grid (I get they're 3D, but you can still constrain them). Movement seems to continue for a little bit after releasing a directional key, which is weird since the player isn't aligned to a grid either.
Combat seemed alright, maybe don't make the first battle against six slimes when you only have one monster with single-target attacks. I got past the first boss but decided to quit at the teleporter maze because those are never fun.
Shows potential, keep it up! I loved playing DWM/DQM as a kid even if I was shit at it.
