That aside, the jump is nice, from what I understand you can only jump if you are against a wall and not moving, I think it's more usual to stick to a wall when you actually move into it (by holding A or D) and then jumping again, but I would not call this clunky but rather personal preference.
Fun game, love platformers, good job!
