great concept! With some polish, it could be a fully-fledged puzzle game, and the aesthetics/environment are lovely. c:
Also, since you mentioned it in another comment: I think the advice I can give you is that when you want to teach the player something without text, it's best to start out with a very limited movement space to highlight only what you want someone to focus on.
I'd also suggest not having the camera rotated at a 45 angle, as that makes it harder to remember which button takes moves me in which direction.
Either way, thanks for the fun. Well done!
