Humm and Strumm is a 3D adventure game in which two players must collaboratively solve puzzles and fight enemies in order to stop the evil Dr. Geoff from taking over the world. Humm and Strumm is set in a psychedelic fairytale world, with lands such as a giant cupcake and a musical forest. The main characters, Humm and Strumm, are armed with yo-yos for weapons. Humm and Strumm has two modes of play: Adventure Mode, in which two players fight Dr. Geoff, and Tag Mode, in which up to eight players play a game of tag using their characters' weapons.
