Linearity

[Finjy]

Hello, big fan of the Penumbra games here. I was just wondering, are the environments in Amnesia going to be mostly linear like those in Penumbra, or is the castle going to be a more 'wide open' environment that you can backtrack and explore?

I'm fine with it being either way but I do think that a large explorable castle would be even more awesome.

Thanks.
