Fantastic horror experience + some suggestions!

What's interesting with puzzles in horror games is that you have to solve your puzzle as fast as you can because a monster could get to you any moment.
In Amnesia it's more like you solve the puzzle and then the monster appears.
This way you would have not only to think hard about your puzzle but also stay alert and watch your own back from times to times.
And for example if a monster spots you and runs to you you have no choice but leave your puzzle, hide, and come back later.
