Nice game, levels reminded me of celeste, which might be good for you but not for me because I suck at celeste too lol. I couldn't get it too far unfortunately, so I don't know if up arrow had any action associated with it, if not then I would have loved to jump with up arrow as well. Plus for tutorial wall jumps, I felt spacing was little far than I would have liked, because I kept falling down. maybe that is my skill issue, but just saying.
I would like to get good at celeste too lol.
