Did you mean Slenderman?
not bad it was really fun
I don't really get what you are supose to do after the intro... All the gates are closed and i can't find a anything to open them..
I admire the idea, and perhaps it is just me, but I find it frustrating how often I go stuck and had to restart, especially as it is hard to see what you are mean to be doing at times (so I spent time thinking there was a way out of a room when restarting as the only option).
Make the text clearer would be my first suggestion.
