"Q.U.B.E. has earned itself a reputation for being a poor man's Portal, which is fitting, but sounds like a harsher criticism than it is. After all, if a game is going to be a poor man's anything, Portal is one of the best possible subjects for imitation. That said, the comparison is actually pretty shallow; the only thing the two games have in common is that they are both first-person puzzle games set in sterile-looking environments. The game mechanics of Q.U.B.E. are significantly different, instead focusing on several types of colour-coded blocks whose unique properties must be manipulated by the player in order to reach each area's exit. For the most part, this gameplay works wonderfully."
