Quantum Conundrum is being developed by Portal creator Kim Swift. It's a first person puzzler in which you play a twelve your old boy lost in his mad scientist uncle's underground laboratory. It's full of safes, switches, lava and vast gaps with no bridges. This would be a serious problem but for the fact that you can switch between five dimensions, each of which affects matter differently. By switching between world on the fly, otherwise immovable objects like safes can be tossed, stacked and even surfed to make it past the mad machines and laserbeams that every mad scientist installs in their homes as standard. It's all demonstrated perfectly in the walkthrough video above from Gametrailers, spotted on RPS. It's out early this year, and looks rather good, don't you think?
