Hey! I enjoyed the art style and the ui, very minimal and cute. The sfxr sounds work great with your art style, too
I feel like you could work on player movement a bit more, the player is very fast and you can double jump your way across the whole level, almost, and if you try to move slowly it's very spazzy, as a short press moves you a long way, and a light tap doesn't move you enough. This might just be a matter of people play testing it to find the fine point :)
Great work!
