Q.U.B.E.: Quick Understanding of Block Extrusion is one of those special games you don't get to see as often as you would like. It's a first person puzzle game, which is rare enough in its own right, but then you combine that with a stark method of storytelling, creative use of environmental puzzles, and an interface that's as smooth as the shiny blocks that make up the levels. What you're left with is a thoroughly satisfying game with masterfully designed puzzles from beginning to end.
