Okay, finished it, it was really nice one.
I was stucked long time before I enter the mines and find that key.
Really complex puzzles in some parts, but challenging and really fun.
What I have to complain was really poorly detailed places some hallways are really empty and ruins the entertainment easily. Don't get me wrong I loved how much work you put those billboard areas and make it look really decent ones.
It was pretty short, but great, not so scary, but nice enviroments and big ones. Nice work man!
Overall: 8 / 10
