Very nice in terms of graphics though the control scheme will need some time to get used to.
Would have preferred if my right hand is the one doing the action and the left is doing movement on WASD keys. Always had the preconception of using space for jumping and doing jump with Z instead felt a bit weird. Had some difficulty getting used to the wall jump, maybe add a reversed force when Z is pressed the 2nd time? E.g. Jump left to touch wall, and when doing wall kick/jump, automatically jump again to right since that is obviously what's intended by the player.
