Wow, it's really cool. I liked the intro, I liked the heroine's character, she's like the horror buff that I am too, always curious. As for the story, I wish we could know a bit more about what the character has gone through, why she lost her father and how did this insidious voice taunt her, as she mentions, is in her head, so it's more psychological? I'm just taking it as that for now. I wish there was a way to have better relationships with the club members though. It's so cliche for horror games to leave the character alone in these types of situations. I imagine those girls would have been interested in the ritual Kat was setting up. Otherwise, game play is smooth, I liked the bendy hallways and subtle scares, atmosphere was great. I would have preferred to have a save button though. Nice job! :D
About the girls - they were interested in the ritual in fact, and even asked Kat to take part in it. She refused of course.
By the way, we don't really know what happened to them. Maybe they haven't gone home but hide instead in one of the rooms to get a revenge on Kat. So the ritual was disrupted and consequences for them were not very healthy. Especially if Kat took the hair from one of them.
