Help Marcelline defend Jake and Finn while they escape from the Ice King and his legion of penguins! Tap the screen to make Marcelline play her axe bass guitar and fight off the sliding penguins. The longer you hold, the higher she flies and can avoid the Ice King’s beams – which you’ll want to avoid because one hit means game over. The farther you get, the more points you can rack up. Red apples and gems give bonus points!
