Ok.. I played it, it's quite short.. nothing really happens, I have NO clue why I was collecting keys.. visually it was nice but there was no story.. nothing scary about it at all to me..
Lots of potential since the environment is pretty well done, but it seems very much like it's unfinished and not fleshed out..
Throw in a story, extend the experience to other environments with some objectives and intrigue and I'd gladly buy it :) .. but the way is currently, it's just a time killer.. and it doesn't last long.
