Nice work! I really like the art style using 2D sprites in a 3D setting. It made it a lot easier to focus on the important elements of the gameplay. I also liked the concept as a whole, and with tutorial levels, I was able to test out each ability in a sort of sandbox environment.
One quick note I would have is simply on the learning curve. I saw some great ideas on separating mechanics out to not overwhelm the player, but I also felt a bit off having to click a keyboard bindings button to figure out the mechanics using a keyboard instead of it just being displayed from the git go. I would recommend different screens with a relevant controls at least before you can begin each level, that way the user doesn't potentially miss learning the controls. A better way to implement this is to have tutorial text displayed to teach the user, but that is a bit more code intensive I know
All in all this is a great game with a cool concept. Excited to see what else you end up working on!
