The Demo is great, I cannot wait to play the full game. I did regret taping up the puppets, it may save bullets, but it was cathartic being able to silence them. I would believe anyone who became trapped there would soon be driven insane by the incessant babble.
I am looking forward to what the game is going to be like on release, it feels to me it is swinging closer to Bioshock. I am really curious to what way the story is going to go, because the gameplay and environment is looking amazing.
