I love Antichamber! Never even thought of it, but "changing suroundings" idea is really adds similarity.
I think all my "Played" library has effect on my game-designing decisions. How else could someone find new ideas :)?
Main inspiration, obviously, were Limbo/Inside for storytelling thruogh environment (though style was lost due to deadline). Oddly Portal 2D had some effect on preproduction, but unfortunatelly mouse-controlled flashlight was cut to ease mechanics. There are a lot more subconsious references, I am sure, like Antichamber and even Alone in the dark :D
Thanks a lot!
