This game has a good eerie atmosphere implemented inside. My only complaint is that the room is quite repetitive. There are some new things like Yuyuko or Mima spawn, but to be honest I like for it to have more just than that. I only manage to clear up to room 50 though, since, for some reason, the Suika doll bite me when I tried to regain my sanity. Not sure if I did something wrong or if there are hidden timers and I run out of time when that happened.
I stream the game here around minute 25 if anyone wants to watch:
