Portal co-creator Kim Swift has released the latest video on her upcoming downloadable FPS puzzle game Quantum Conundrum.
The demo shows how various elements of the game’s complex puzzles work, such as switching dimensions on the fly to reach new areas and activating slow motion to help complete puzzles.
The game is being developed with independent developer Airtight Games, and is expected for release Windows, XBLA and PSN in the next few months.
