Very fun experience! First of all being able to choose your abilities is a super interesting idea (idk how well it fits into the Metroidvania genre but it's cool anyways), second is that besides the odd control scheme I liked the feel of the game. I would recommend changing some colors so the player and enemies / objects don't blend into the background (which is an issue people had with my game too), and keeping pixel sizes more consistent whenever possible so it doesn't look jarring to see big objects because they're made of the same size pixels. Overall I think it's pretty nice.
