Alter Ego: DreamWalker(2013)

Alter Ego: DreamWalker is the sequel to the 2011 action puzzle platform title Alter Ego. In this game, you have a phantom 'alter ego' that mirrors all your moves (either horizontally or vertically) from across the screen. You can switch between the hero and his alter ego a limited number of times in each level, in order to avoid enemies and reach otherwise inaccessible positions. The ZX-Spectrum version uses multicolor, a software technique to combine more colours than normally possible without colour clash.
