First off, this game looks gorgeous, congrats on that! All animations look fantastic and the general vibe fits really well with the animations for the story. Although it can be a bit disorienting because of how the 3d models and 2d sprites interact sometimes, with a bit of tweaking and maybe a shadow for your character it could be fixed.
Gameplaywise, I thought the game was pretty engaging. Hitboxes can feel a bit larger than they should be, and the wall jump thingy can feel a bit odd at times since you fly up really high when doing it. This sometimes left me feeling like I wasn't really in control, but it's nothing a bit more balancing can fix.
The music you chose suits the tone really well. I would have liked to see some sound effects thrown in there too, since it can also allow you to have a more visceral understanding of how your character functions. Things like having a jump sound that's timed to how high you can go or things like that go a long way in making you feel the game more tightly.
Overall, I liked it a lot! Keep up the good work!
