This will be the place to discuss the architecture of the building.
Basically, the terms of the test of courage is for the player to enter through the main door of Block A, enter into Block B using the covered walkway that links Block A and Block B.

I wish I can have a real abandoned school as a model, but I'm only planning to go to Akita late next year :( - Ai-chan
