Puzzle games need ‘eureka!’ moments and Bridge Constructor Portal has those in abundance, counteracting the progressively difficult levels. So come and join the testing team at the Aperture Science Enrichment Center, where you can destroy stuff, have fun and feel pretty darn smart in the process. Oh, and we have cake!

Bridge Constructor Portal is a fantastically challenging puzzle game that is dressed in $10 looks. You will not be awestruck by anything the game does, but the challenge will have you wanting more, the humor will keep you smiling, and the silly horn at the end of the level will be enough to know you did it.

Bridge Constructor: Portal is a wonderful game that fans of the Valve saga and those looking for a challenging puzzle game will love. Fun and satisfying, with everything that characterizes a title of the Portal saga.

Sure, having something with more narrative and GLaDOS would have been welcomed, but like most puzzle games, I accept it for what it is, and you’ll get what you want out of it if you’re a fan of the genre. It would have been easy to simply throw a Portal paintjob on top of the base game itself, but they’ve gone beyond, adding many of the core mechanics from Portal and implemented them in clever ways, especially since this is played in 2D.

It would be unfair to value this game as what it is not, or what we would have liked it to be. But the final result presents us with a more than remarkable puzzle game, challenging and absorbing. Bridge Constructor Portal takes the mechanics and physics of the work of Valve to enrich its studied formula greatly and remind us that there was a day when the company of Gabe Newell made great games for the memory.

A cool, well-executed Portal spin-off/mash-up, Bridge Constructor Portal takes one of Valve's dormant franchises and neatly transposes it into an appealing and enjoyable puzzle game. Next up, Bridge Constructor Half-Life? Play it. For science.

Bridge Constructor Portal is still Bridge Constructor. The inclusion of GLaDOS, dark humor and Portal staples like gels, turrets and companion cubes will be appreciated by fans, but it's not enough to overcome the tedious core gameplay. Once you have the satisfying 'a-ha!' moment of solving a puzzle, you come to the unfun part: painstakingly piling up dozens of little triangle formations to create supports for your structures. The formula gets old quickly as the puzzles start to require more elaborate building, and we come back to that word: tedious. Players who know they enjoy Bridge Constructor will be at home with Bridge Constructor Portal, but those who disliked past games in the series should steer clear, despite the tantalizing Portal branding.
