Alright mike, you wanted to know what the inside of Minatodai Dorm looked like so I made a terrible video because it is easier to see it than just read about it.
https://www.youtube.com/watch?v=b3KKYk5vxKIChanges from the original in the video so far:
On the right wall of the dining area on the first floor is a door leading to a fairly large kitchen.
The door in the indented section of the back of the first floor dining area leads to the basement... And by basement I mean underground time space labyrinth.
The second and third floor hallways get longer and add rooms based on the number of occupants.
There is a red door on the back wall on the second floor entry that leads to a sort of armory where Minato stored all the weapons and armor he has collected.
There is a yellow door on the back wall of the third floor entry that leads to a treasure room where Minato keeps all the gold, jewels, treasures, and artifacts he has accumulated.
The roof access now leads to a kaleidoscopic vortex of colors... I mean DOOM!.
The front door leads to any of eight locations in the city based on where you want to go, it is random if you aren't wanting to go any place in particular.
EDIT
Before anyone says anything, I am aware that the video is shit. It was the first one I have ever made ever.
Also sorry it took so long, I had a pile of studying and exams to deal with. That is basically done so all I have left is labsim catchup which I can spread out a little.
