Well, I'm from North-Western Scotland. I love to play games, make games, buy games, eat gam- Wait... No. That's not right. But I hope to one day work for a nice cosy company... Possibly begining with a 'V'.
It really was not fun at all. I was looking forward to this mod, but if you add up all the problems (I can't even start to list them) you'll undersand why I rated it so low. The gameplay was so bad that I had to actually ragequit the tutorial and start playing the actual game...
Better luck next time. My advice would be to take your time with maps and when you have a solid layout, change it around to make more sense. In the beginning I went straight to the bottom floor and found the key, and it was only after my first attempt that I realised it was a key. I then went back to the top floor and tried all the doors. There really should have been something guiding me to the locked door. Make it more linear, but still appear to be open.
