Should I buy this game?

I played the Amnesia demo with a friend today and we had a lot of fun :p we turned off the light of course. He started playing but after 1 minute he asked me to continue, lol >.<
Anyway there was a strange bug in the demo that caused the entire screen to flip upside down, so we were basically walking on the roof. It made the game less scary and more difficult because it was hard to solve some of the puzzles and we got lost quite a few times XD.
I'll probably start playing the full game tomorrow. 3-4 hours a week, 20-30 minutes for each session .
It's definitely a very scary game but I think that if you beat this game, it'll also help you in real-life (if you're not an "I-eat-horror-games-and-movies-for-breakfast" guy already ).
