A demo of Kim Swift's reality-defying puzzler Quantum Conundrum is now available for download via Steam. This is a great chance to get hands-on time if you're in two minds about making a purchase. The Airtight Games-developed puzzler had Kim Swift as its lead designer, who formerly served as lead designer on Valve's Portal. The game released back in June 21 on Steam, and is due out on PS3 on July 10, and Xbox 360 on July 11.
