Really fun game. great level design .
suggestions:
okay so, I think you should change wall jump controls a bit something like if player presses "W" then jump and if player presses "w" and "A/D" together then also jump. (in short make it so "w" + "A/D" is also valid for jump)
and yeah one more thing about the jump make it so you can jump even when you are resting on the wall ( pressed Lshift ) .
(cuz its really bothersome to release whenever jumping and it would be better if it would be like I just need to hold shift whenever I need to wall jump)
