The Fluffy Dimension. Notice the fluffy bunny suit on the wall?
Of course, this simple example barely scratches the surface of QC's fertile concept; its core dimension-shifting gameplay provides a seemingly endless selection of inventive challenges, all of which are extremely satisfying to solve. Additionally, even the most mind-melting puzzles are fair and logical, and will leave most wondering why they didn't solve them much sooner. All that said, a few brain twisters do rely a bit too heavily on precise platforming; the controls never approach the clunkiness we've experienced during certain first-person shooters' unforgivable jumping sections, but trial-and-error tedium does occasionally trump the fun. Thankfully, a generous checkpoint system should ensure most players don't frustratingly plant their controllers in the plaster.
Despite this single--albeit occasionally fun-halting--flaw, QC's inspired concept, superb pacing, sound mechanics, and Pixar-rivaling presentation should keep players' giddily engaged for a good 6-8 hours. Hidden collectibles and a number of performance trackers also guarantee completionists and leaderboard squatters alike will find plenty of incentive to replay previously conquered puzzles.
Quantum Conundrum doesn't quite reach the genre-defining quality of Valve's juggernaut, but at $15, it's a bargain-priced no-brainer for fans that enjoy taxing their minds as much as their thumbs.
