Update: You can see a handful of new Quantum Conundrum screens alongside the E3 trailer for this first-person puzzle game with Portal roots.

Original Story: There's more to Quantum Conundrum than its physics-based puzzles. It's also home to a variety of offbeat characters including the eccentric inventor/genius Professor Fitz Quadrangle and the newly revealed furball, Ike. Get to know the little guy in an all-new trailer.

In addition to showing off Ike, Square Enix has revealed the release date for the PC version of the game, which is hitting June 21. There's no word on when the downloadable game will be available for the Xbox 360 and PlayStation 3.

Take a look at the trailer below to see Ike (and the game) in action. We're told that no Ikes were actually harmed in the making of the game, so you can breathe easy.
