Played through this spooky map to no avail. There's a door at some point that doesn't trigger (luckily the npc ghost inside the room opened it by force) but then the map stalls there when you kill it.
Because everything is in japanese, I do not know what to do next or if the map is broken.
I suspect it is broken since after that last ghost, only one thing is left to explore and that is the rooftop/terrace. Some bars are blocking the ladder and they should break to let players pass. Even then it is broken since the stuff you must break has an invisible wall. Again cheated to break it.
But sadly, after triggering everything that was left, nothing happened, just some more ghosts spawned and some japanese text appeared again.
Plus there's an infinite spawn of a "morimaki" (babygarg) in the bathroom. That just does nothing.
TL;DR map is broken and unfinished
