I was definitely creeped out in the beginning! Then I got the gist of it and I realized that the creepy dude was never going to attack, and the maze keeps teleporting me around.
Is it possible to find your dog? I didn't, I played for atleast 15 minutes. Once I realized it wasn't a normal maze and the dog sound probably didn't mean anything, I just didn't have the motivation to keep looking. Everywhere I looked, I had already been.
At one point, a tornado of crows made me restart (?)
So definitely a creepy game, but I would have liked it more if the maze was "fair".
