Pretty interesting game. The buttons feel juicy and that's nice. I just think that the speed of the player character should be a little slower, since it's important to have precision while jumping over or on top of enemies. The gravity also felt kinda low, but that's not a big deal since you chose it to be. It also isn't quite original, but it's still well made for a game jam. Very nice sound effects and the level selection! The scoring system is also nice.
Good job overall!
