I liked the concept and the puzzles were good. The art and music created a good atmosphere.
I had an issue where the text to tell you about the abilities was often at the edge of the screen, or even partly off screen, even when you needed to know what it said before you got the ability it was telling you about. I think it would help if your tutorial was a bit more direct. For example, when you go from activating an ability while on the ground, to needing to activate right after you get it, I think it would be good to tell the player something along those lines, and have that text above where the player starts, rather than most clearly visible as you are getting the card.
