Set in a mysterious and abstract sterile environment, Q.U.B.E. (Quick Understanding of Block Extrusion) is a first-person puzzle game that challenges players to navigate each level by manipulating coloured cubes that surround them. There's little to go on as the game begins - the player is dropped into an all-white room with few instructions, and simply has to figure their way out. The tone of game changes as the player finds small and big alterations to their environment, supported by an original score, inviting each player to let their imagination take over as to where they might be. Through experimentation and discovery, players will progress through an ever-evolving series of cube puzzles that will challenge them with logic, physics, platforming.
Better then Portal. Nuf said. :)
Ok, so some details. Lots of environment manipulation. Puzzles are top notch. I found them requiring more brain power then Portal's puzzles (seems to be the benchmark for first person puzzle games). There is dialog between two characters that talk to the player and they're voiced very good, but THE highlight is the puzzles.
If you like puzzle games, get this one. :)
