My only problem is the enemies are a little difficult to fight with only a punch attack because how much they bounce, will you add anything new in the future?
Actually there is abilities that you can unlock, get 50 red thingy (the thing that you can collect) and find a giant red orb on one of the map. I made some abilities that you can unlock with that.
Those abilities are :
-A shield (more an AOE than a real shield buuuut)
-A projectile ("bullet")
-Double jump
