The game never takes itself terribly seriously, which makes it ideal for short play sessions but a little unsatisfying to complete; all the jokes and visual gags feel like window dressing for a mildly challenging puzzle game. Quantum Conundrum never really explains why you should care about the fictional Quadwrangle family or their fantastic estate, but it blatantly challenges you to play through puzzle rooms multiple times by scattering collectibles throughout the game, measuring your performance against your friends via online leaderboards, and placing a big honking “Level Select” machine smack dab in the foyer of Quadwrangle Manor.
Thankfully, the puzzles are a blast to solve. The design of the puzzle rooms encourages you to play with the Quadwrangle estate in unexpected ways; by quantum shifting between alternate dimensions that make everything (except you) lighter or heavier, reverse gravity or slow down time by a factor of ten, you’ll quickly start solving seemingly impossible conundrums by making cardboard heavy enough to stop lasers, slowing down time enough to play catch with yourself, or rapidly reversing gravity back and forth to surf through the air on a flying sofa. The puzzle rooms get more complex as the game progresses, but I never felt frustrated; in fact, I often found myself grinning after discovering a solution to a seemingly impassable puzzle.
None of these puzzles are likely to stump you for more than five or ten minutes, but if you finish Quantum Conundrum and still want more you can go back and replay levels to try and beat your best time or solve a puzzle with as few quantum shifts as possible. Your performance is broadcast to your friends via the afore-mentioned online leaderboards, and going forward more puzzles or multiplayer modes may be released for Quantum Conundrum as downloadable content. Hopefully Airtight Games will also release some DLC that fleshes out the story of Dr. Quadwrangle and his errant nephew; after completing the game on PC I was a little disappointed with the lackluster ending, but thoroughly enjoyed the seven hours I spent solving the riddles of Quadwrangle Manor. I think you will too.
You can download Quantum Conundrum on Steam right now, or wait and download it on Xbox 360 and Playstation 3 next month.
