Prepare Yourself. For Life On the Wall.

You're at the bottom of an impossibly enormous wall. Your village is at the top. To get there you're going to have to manipulate the blocky surface of the wall (and beat some bad guys and other random stuff).

The game's called Against the Wall. It's for PC and Mac, and you can download a free, current build of it here.
