I like it! Beat the game in about 20 min. I think the punishment for failure is a little high in some places. A one hit KO is pretty punishing, especially when you need to restart from a checkpoint really far away. I think this could have benefited from a life system, beginning of room checkpoint system, or both. Another note, you need to hold down the run button to wall jump up the same side of a wall which is not well explained. Also, the run button is only beneficial, leading to it being held down the entire time while playing. I think removing the run button and setting the player base speed to the run speed would be better (less finger fatigue). Overall, nice game! I think I will try hard mode soon.
