I'm sorry, but this game... is horribly broken for me. I don't know if it happen for me only or for other people, but yeah, it happened for me, on my own laptop, I'm not sure if it happened like that for others tho...
Yeah, the game is REALLY GOOD, the story, the plot, I'd rate it 8/10.But...
Bugs that i've experienced:
*SPOLIER*
1. If you play as fullscreen to the part when you just entered the Mansion, the game tell you to go the dining room to talk, after that you walk out to any door, the screen would just turn black, you can see the dialouge from Haru: "What was that unlocking?". I fixed it by playing on windowed screen.
2. If you successfully got the Good End (All 6 friends saved), you get to play as Yukio. Ok, so everything is normal up until you enter the mansion. If you walk to the living room on the right, it would trigger the scene where you play as Haru and ask everyone about Mark's death, your character is still play as Yukio, but you would talk to everyone as Haru. Also, the game will play the cutscene where you walk upstairs as Haru, and Saki disappear, if you accidentally trigger the scene when you discovered Saki's and the other guy's death in the bath tub, the monster will appear and annoy your ass and you can't process the story. I got the 3rd picture, and i was talking to the spirit and the monster walk over to me wait for me to done talking with the spirit then it killed me, and the game even tell me to save before that, which means i got SPAWN KILLED EVERY TIME I LOAD.
That's it, i can't proceed the game anymore, they didn't even have walkthrough on youtube, dang it. It was a nice experience though.
