Quantum Conundrum is looking like a pretty solid first person puzzle game. The gameplay and graphics come from some of the same folks who brought us Portal: Still Alive. With a trailer like this and such a strong pedigree our expectations are sky high. Whereas Portal had a rather dark feel this seems much more light and funny. We suspect that the puzzles will still be rather devious though. It is scheduled to release sometime this summer so keep your eyes open for more information as it becomes available.
