In the game, the player controls Princess Bubblegum. Pressing Z or the space bar allows you to jump, and pressing X allows her to throw potions. Jumping from platform to platform, the object of the game is to avoid enemies and collect as many mushrooms as you can. In order to pass from one level to the next, you have to earn a bronze medal by collecting a certain amount of mushrooms. Collecting mushrooms gives you potions to throw, and fills a gauge on the side of the screen. The gauge resets if you get hit by an enemy, but it doesn't take away the potions that you have. Potions can be thrown and used to defeat enemies.
