I love the art style and the game was quite fun to play once I figured it out 😄, an explanation of the game loop might help with that in the description if you don't have time during the development stage.
I noticed people already mentioned normalizing movement so I'll mention something else... Yay constructive criticism! I may be wrong but the player's side way animation seems to be clipped slightly at the end (ie the last animation frame doesn't stay for long). I find that in Unity's animation system if you duplicate the last keyframe so it lasts double the time you don't end up with the last frame flashing like that. I could be wrong and you might have already got that but I think I noticed it... Let me know if that doesn't make sense.
Either way this is a very cool idea and the art is great (as I mentioned earlier), let me know if you need me to explain further what I said above or if you want any help on future projects (I've been working with Unity for quite a while)!
Also let me know if you publish a devlog so I can check it out and give you a higher score on that section!
