This game is great, the art style is fantastic and the gameplay is fluid. It's simple, yet difficult and, the speed at which you can quickly get back into a new run really helps with the flow of the game as a whole!
The only thing I think could be improved is some kind of guide to help understand what the abilities do? I Ran into a few where it took me a little bit to figure out what they were actually adding to the gameplay, although that's mostly a minor issue. Overall, this is a great game and a great experience!
