Oh yeah. I started writing this a few years ago, then forgot all about it. I only now remembered it again when I was cleaning up things on my hard drive.
So this is basically a list of all the things Alex thinks to himself when examining things in the levels. It's incomplete - only up to Nightmare Church or so, but most of the game is there. I don't think something like this was published before? Well, enjoy:http://pastebin.com/R6HsBj91
