I love your spooky music and the atmosphere of the game as a whole, and I enjoyed it when I started playing. However, it may be possible to add some hints that the Joker has collected the number of balloons or the height of the jump to help the player understand the game. The rhythm of the music in the game is consistent, and it may be possible to provide some tension by making the rhythm of the game music faster as the player goes deeper into the game. The platform distance at the end of the second level may be a little too long, I tried many times before jumping over, maybe I can put this kind of spaced platform in the last level to increase the difficulty of the game.
