I respect any dev who is working on a 3D action game like this, but the lack of polish on virtually everything is pretty hard to get by. The game controls well, I think certain movement options and attacks need to be tweaked a little further to be more user friendly. The animations could definitely use some more weight to them, and the effects of attacks could be amplified so everything feels satisfying to pull off.
The U.I and environments feel more like placeholders, more so the UI, but that makes sense given how you've probably been focusing on the gameplay and the design of the player char. Her design in particular isn't my thing but I think objectively you did a good job.
Some better sound design + music will also elevate things a lot but I'm sure you have that planned in the works. Overall it feels like you've designed a sandbox to mess around with, and thats probably the smartest thing to do with a game like this. Tighten everything up and focus on making the basics smooth and enjoyable, the rest will follow for sure. Excited to see more!
