Quantum Conundrum."
Game Informer gave it an 8.5/10, while praising the game saying "With its physics-warping mechanics, thoughtful brainteasers, and playful atmosphere,
Quantum Conundrum should appeal to the legions of
Portal fanatics." Bob Mackey of
1UP.com gave the game a B−, but stated: "But even in a vacuum, Conundrum's brilliant moments are hampered by an inconsistent world, an emphasis on performance rather than ingenuity, and a level of humor that wouldn't be out of place at your local pre-school." Some may complain that it's not as funny or as clever as Portal, but
Quantum Conundrum is a unique experience that deserves attention nonetheless."
IGN gave
Quantum Conundrum an 8/10, praising the clever puzzles but criticizing "lack-luster" environments and the game's ending. ==Legacy==
