I love the art so much, it looks fantastic.
The game plays well, the controls are nice and simple but there is a lot going on so it doesn't feel boring.
My only feedback would be maybe add a screenshake to show when you've been hit because i didn't realise i was taking damage.
The player colour changing when you're hit is usually atleast a good part of that but if you're looking at everything else on screen it can be hard to know if you've taken damage without some kind of screen wide feedback and a sound.
Game is fun though, good job!
