Alright, since no one has made one yet, here it is:


The sliding wall in Yuyuko's room
- There seems to be nothing in Youmu's room though.

The interactable monitor that plays both their themes
- It stops if you go too far away from it.

The left part of the wall in the main hall is also a prop
- Still, I can't find a way to open it yet.

A drill buried in the dirt that can be picked up near the spawn point
- Obviously used for opening something.

The bushes have some sort of prop properties
- They're all scattered, and interacting with them will probably do something.

A switch-like outside the walls of Hakugyokurou
- I still don't know what it does.


My friend also told me that Yukari is in this map, but no luck yet.
