You made it! You're at the "Gates of Heaven" a series of arching stone gateways constructed as a kind of monument (and retroactively re-purposed into an excellent tourist trap). As you wander through the interlocking arches, it is hard to overstate your satisfaction at having successfully navigated a strange city.

What do you do?
Head back to your hotel for more exploring tomorrow
You're done. It's time to head home (bump)

[I probably don't need to tell anyone how great the Portal franchise is. But I love puzzle games, and this is one of the best ones out there from the smooth use of a clever device, to a script that has both humor and heart while employing just a few voices, to a multiplayer mode unlike any other I've seen. Have fun with this one.]
