Thanks.
Yeah, maybe I made the third room puzzle a bit too difficult. But, if you want to keep going, I can give you a hint: the titles of the books (the ones that have one or two words) will give you an indication to where you have to position and press Z. I'm sorry you found some of the stuff a bit gratuitous, it's just that body horror and SA are the two things that scare me the most, that's also why I put an "adult" tag.
But I'm glad you liked it overall. Thank you.
