The game is based on Sleepy Town Manufacture's So Twenty One. Used by permission.
You'll need Allegro and Visual Studio to compile it. It probably won't work anyway. You may have to go back a few commits to find a stable version. (I believe I was in the middle of porting collisions to Box2D when I stopped working on the project.)
