Tearaway is a third-person platform game which utilises almost all of the PlayStation Vita's features in some way. In one example demonstrated in the game's announce trailer, the player encounters an elk who needs a new skin. The player is able to take a picture using the PS Vita's camera and have it applied to the papercraft animal. In a gameplay demo at Gamescom, Media Molecule demonstrated how the player is also able to use the PS Vita's rear touch panel to effectively push their fingers up through the ground to interact with enemies and the environment. In another part of the demo, the player draws on the touchscreen with their finger to cut-out a paper crown for a character in the game.
