Inside

Game plot - Inside

Inside is an atmospheric 2D side-scroller puzzle platformer in which, hunted and alone, a boy finds himself drawn into the center of a dark project and struggles to preserve his identity. The unnamed boy explores a surreal and mostly monochromatic environment presented as a 2.5D platform game. The game is dark, with color used sparingly to highlight both the player and certain parts of the environment. The game is also mostly silent, with the exception of occasional musical cues, the boy’s vocals, dogs barking, equipment and sound effects. The player controls the boy who walks, runs, swims, climbs, and uses objects to overcome obstacles and progress in the game.
