I was really bored the first 10 times or so when nothing happened but decided to stick through it and it started getting more creepier from then on. This is the type of game that makes you want to look behind when walking and makes you question am i prepared for what's ahead ? I would say the shadow people or dolls made it less creepy for me later on, more than anything the sounds were much scarier.
Also, love the shout out in the end to play other people's game. That's awesome!!
