I don't know why no one played this yet but this is really good
The art is nice and the mechanic is really fun to play and the controller is accurate.
The music also fit with the game well, if there's anything, maybe design the enemy so that they communicate to the player that they're meant to be jumped on. Adding moving enemy could really spice up the gameplay ( I haven't play through the entire the game so I don't know if you did add them, if you did then ignore this xD). Overall great game, good job!
