Actually, I've encountered the screamer. I'm not sure if this is what triggers it or not but for me, it happened after (spoiler marks in case you want to find out for yourself)
playing The Loop on the protag's laptop, pressing X when the game tells you to, and then BAM--screamer!
Afterwards, I've encountered the screamer when (again, in case you want to find out for yourself)
watching TV, or hanging around the TV area.
Once you know to expect him, you can just block the screen with your hands until after he pops up, but if you forget it's really, really creepy.
Though not as creepy as
the mannequin whom I think wants to kill me, but I haven't summoned up the courage to make it past the point where he's standing above my bed with the knife.
EDIT: No, wait, I finally did it and...game over.
Or is it? The game over screen abruptly stopped and I could only rewind, which got me in...hell?
...By the way, do you plan to release a hint guide for the puzzles? I think I've figured out how to solve the first one, but I'm not entirely sure because I can't quite get the right set of numbers. What I picked up from the clues was:
. I need to examine the pictures
. The combination is somehow related to these pictures, and possibly to the telescope (stars?)
. The scraps of paper with dates are related to the combo--perhaps each date is related to the painting that's out each time you wake up?
