I played Penumbra: Overture, one of their earlier games, and I was really, really pissed off at the control scheme for moving objects in 3d.
I'm not sure if any of you guys remember the old mid 90s game Trespass, or Trespasser, I believe, some sort of 'virtual reality' wannabe game with an island of dinosaurs, but some of the selling points included no HUD, no ammo counter, aside from the female character counting out loud, and almost the exact same manipulation of objects in 3d space, picking up rocks and tools etc. It was annoying then, and it's still annoying now.
That control issue aside, I thought Penumbra was still a very good indie game, I bought it in that Indie sales bundle awhile back where you name your own price... I gave 30 bucks for the 4-5 games(I think they added one afterwards.)
Amnesia looked graphically much improved, but very similar to the Penumbra series, so I didn't buy it or even try the demo yet. I was hoping to get used to the 3d control scheme enough in Penumbra to not totally cloud my opinion of Amnesia.
I am still debating whether or not to get it, but I have to ask, is EVERY company aside from Blizzard basically about to fail if their game doesn't sell X million copies the first week? What is wrong with this industry?
PS. Amnesia makers, the biggest problem with your game is your horrible 3d control for object manipulation... just my opinion.
