It's so close.
I love the art and style.
The music suits the game well.
I would totally play this game in my spare time for fun if not for the follow....
You need tighter platform controls if you're going to have platforms dangling in the air.
I slid off the platforms a tonne because of the deceleration. (You can check out the devs of celeste for a good example of how to do platformer controls.)
Oh, and your spikes look almost exactly the same as a ore node after you've mined it. So I lost health a couple of times not remembering which was which.
