Quantum Conundrum is a first person puzzle game in the same vein as Portal and Antichamber (which I reviewed for the letter A), and actually shares a lead designer with the former. Because of this, comparisons are inevitable. The good news is that the comparisons are largely favorable. If you enjoyed Portal, you’ll most likely enjoy Quantum Conundrum.
When you are dropped off at your eccentric uncle’s mansion, things seem a bit strange. Your uncle (voiced brilliantly by the amazing John de Lancie of Star Trek fame) is nowhere to be seen, but you can hear his disembodied voice speaking to you. He explains that he has been trapped in a parallel dimension and tasks you with rescuing him using his new invention, the Interdimensional Shift Device.
The rooms of the mansion are filled with physics puzzles that require the shifting of dimensions to solve. The first dimension you have access to is the Fluffy dimension, where things are much lighter than normal. This allows you to lift objects you wouldn’t otherwise be able to, thus moving them to switches on the floor that are triggered when you switch back to the normal dimension.
There are four alternate dimensions in all, and puzzles later in the game require shifting between multiple dimensions in the same room to solve them. It’s fun not only seeing the different look of the dimensions, but also playing around with throwing things to try and solve the puzzles.
All in all, this is a pretty good companion game to Portal. I liked it more than I did Antichamber, and I’d recommend giving it a try if you liked Portal.
