Red Matter sure is good at building atmosphere so far, it's quite impressive to me! 
I'm only half an hour or so into the game but it's interesting, I want to know more about what's going on and it's a bit spooky too.

Without spoiling the game, does anyone know roughly how long it is? I'm not a very quick player, I tend to slowly take my time and autistically look at everything, so the little hand scanning/translating tool is great for that, so how long do you think it'll take me?
