Crush is a platformer-puzzle video game developed by Kuju Entertainment's Zoë Mode studio and published by Sega in 2007 for the PlayStation Portable. Its protagonist is Danny, a teenager suffering from insomnia, who uses an experimental device to explore his mind and discover the cause of his sleeplessness. Each level of the game, representing events from Danny's life and inspired by artists such as Tim Burton and M.C. Escher, requires the player to control Danny as he collects his "lost marbles" and other thoughts.
