Enter the Aperture Science Enrichment Center and experience Bridge Constructor Portal – the unique merging of the classic Portal™ and Bridge Constructor™ games.

As a new employee in the Aperture Science test lab, it's your job to build bridges, ramps, slides, and other constructions in 60 test chambers and get the Bendies safely across the finish line in their vehicles.

Make use of the many Portal gadgets, like portals, propulsion gel, repulsion gel, aerial faith plates, cubes, and more to bypass the sentry turrets, acid pools and laser barriers, solve switch puzzles, and make it through the test chambers unscathed.

Let Ellen McLain, the original voice of GLaDOS, guide you through the tutorial, and learn all the tips and tricks that make a true Aperture Science employee.

Really fun!

I absolutley love bridge building games…but they can become mundane building triangle structures from point A to B. This game totally refreshes the idea with a Si-Fi feel. Me and my PhD physics friends have gathered around my laptop trying to solve every level!

One feature request:
Save progress accoss devices of the same user.

Fun game! Frustrating lost game state issues

This game is tons of fun. 5 stars for fun.

However, my progress has just been reset and I was forced to start all the way from the beginning with the latest update. This is really dismaying!

The good:

- Glados :)
- Portal theme!
- A few laughs
- Easy controls
- Easy to learn
- Building bridges is fun!

The bad:

- Some levels are less about planning and endlessly tweaking a set of planks to bounce a ball in to the exact right spot. This is more tedious than it is fun. And… sometimes, for some reason, you’ll put a plank somewhere else in the level and it will change the behavior of your ball bouncing planks, so you get to repeat tedious unfun plank tweaking.
- Bugs (lost save game state! I have had to start over from the beginning twice now. Ugh!)
- Inability to export save game state, or multiple save slots (my kids share an iPad, would be nice if they could play the game on their own progress).
- Support page “intentionally left empty” - lol. Nice. Cool. So I guess I’ll just rant in the reviews instead.

Fun for a while, but the bugs are ruining it.

I bought this app on my Mac and was instantly hooked. Very fun game.

Then I saw it was available on iOS as well, and, not wanting to miss out on the fun when I’m on the go, I bought that version, too.

However, you can imagine my disappointment when I found out that my saved status from the desktop version didn’t sync to the iOS version. Instead, I had to start over again from scratch.

Developers, please add the ability to sync savegames using the cloud!

Update: just like many other users reported, after installing the most recent update, my savegame has been deleted and all my progress has been lost. I was somewhere around level 25 or 30 and I’m quite reluctant to replay all of them again.
