THE WALL 墙

This game was very vague to me so I decided to include a small guide in case anyone else is confused.

The game can be 100% completed by not using a gun (Nonviolent Resistance achievement) and at the credits screen walk through every famous building (Big Ben, Eiffel Tower etc).

To reach the end credits you have to hit guards when they're not looking at you to steal their keys. You can then break open walls, input the key, and type the code (Facebookk etc.). Once you have opened all walls, the walls/floor will collapse.

To understand what I mean better you can use Xeinok's video as a reference, see the last 10 minutes here:
