The Spectrum Retreat does for colors what Portal did for physics. It’s a puzzle game that presents a series of rooms which must be escaped by figuring out the convoluted logic of colored boxes, bridges, ramps and gadgets. In its first-person view, the player is also part of the puzzle, becoming one of the colors by touching objects and so swapping their hues.

It’s a neat idea that’s mostly executed well. The puzzles don’t have anything like the charm or originality of the Portal series, but they do offer intrigue and satisfaction. It’s the sort of game that’s fun to play for an hour, and then leave for a while.
