Alter Ego: DreamWalker is the sequel to the 2011 action puzzle platform title Alter Ego. In this game, you have a ghost 'alter ego' that mirrors your every move (either horizontally or vertically) from the other side of the screen. You can switch between the hero and his alter ego a limited number of times in each level, to avoid enemies and reach inaccessible positions. The ZX-Spectrum version uses multicolour, a software technique for combining more colours than is normally possible without colour clashes.
