Echoshift is a spin-off of the popular PlayStation Network game echochrome. It was released for the PSP and PS3 platforms in 2009, offering players an innovative puzzle experience that challenges their ability to manipulate light and shadows. The gameplay revolves around controlling two characters at once - one on the foreground and another on the background - as they navigate various levels with obstacles. Players have to use both characters together in order to reach each level's goal, using objects such as mirrors and other devices to manipulate light rays so that they can progress further into each stage. With multiple modes, unlockable content, online leaderboards, and a unique visual style, echoshift provides hours of exciting puzzle solving action!
