Shift Happens is a puzzle platformer focusing on cooperation, with gameplay tuned for either single-player or on-the-couch multiplayer play. At its core the game revolves around the “Shift” and the two protagonists “Bismo” and “Plom”. Bound together by accident, they can shift their masses between each other. If one of them shifts, they both change their sizes: the big gets small and the small one gets big! This core mechanic allows for challenging puzzles and funny interaction between the players. Cooperation and communication is the key to succeed.
The game consists of four stages: the laboratory, the forest, the canyon and the grotto. Each with a unique art-style and gameplay. Shift Happens encourages two players to play together and collaborate to finish the game, but it also comes with a singleplayer mode that has a whole different set of level content.
