Q.U.B.E., the visually stark first-person puzzle game based around manipulating the titular cubes, was released yesterday on Steam. A 20-minute demo showcases the basic mechanics of the game — namely, your character's ability to extrude and retract blocks with different properties from an abstract environment. The full game is currently $12.74.

The game is backed by the Indie Fund, a group dedicated to providing money to indie developers without the restraints of publishing contracts. The Indie Fund includes such gaming luminaries as Jonathan Blow (creator of Braid) and the creators of puzzle game World of Goo. While Q.U.B.E. is the first Fund-backed game to see release, the group is also supporting a remake of interactive fiction game Dear Esther, which will be released in February, and the upcoming heist game Monaco.
