I love it, this is a pretty original idea. I learned the game immediately in my first try when the slender man enter and his description appear, read it and lost. (Don't know if that was intentional, but was funny for me)
I really like that it have 2 perspectives from in and out. And have to learn the sounds when out.
Really fun, I don't know if having a little display of how many floors the monster is staying will help with the gameplay but that's something that come to mind while playing it. Good work!
