Really like the art and music. The jump is very satisfying and has a lot of potential. Some kinks to work out around the game feel (bumping the corners of ledges feels bad etc) but it's a very enjoyable, novel movement system. I can see long levels where you build up a lot of momentum with the spacebar being really really fun. Great Submission!
I would also love it if you could check out my game and let me know what you think!
