This is a really nice celeste style game! The art and music are really amazing for a game jam. I really love how wall jumping moves you more horizontal than vertical. I think that's a really cool mechanic that opens up a lot of design space for you.
I think there should be a way to unstick from the wall. Maybe if you just input a direction away from the wall when you're stuck do it you can disengage from it? Also I think it's not clear if you can progress downwards or if you'll fall to your death. I think there was one sequence when that was the intention because there were spikes down certain paths, and I don't have a problem with that actually. But there are other situations where it's not clear if there is more level down there or if you'll just die. I think hollow knight solve the problem really well by giving subtle visual indicators if it's safe to descend downwards.
Really nice game. Well done!
