Can anyone give me a hint where to look for it, please?

I'd love to play this game, but I would like to know the length of it basically. Is it short and quick to the point? Or does it take time to solve the puzzles and figure out the story? I'd just like to know before I buy it.

Does it have it?

Not bad, some good puzzle design that had me stumped for a bit until I figured out the trick. And neat plot twist regarding who the killer was, even though I kinda suspected it. But way too similar to PT. I did however like the part "Not this sh*t again, let's change the channel!" very muchj. It made me burst out with laughter. Was that a subtle stab at the fact that there actually are way too many PT clones?...

after pressing start the camera goes into the tv. and there is knocking on a door. May someone tell me why this is happening? Anyone else have this problem?
