Absolutely! I'm curious tho, how many endings there is? 2?
At first I was moving around clicking every single tile and block trying to figure out what I did miss. I even ran around for hours trying to go through different ways while the monster was chasing me. Lol I even tried to get him stuck at the way out door, I stood there for a while thinking if I don't open the door maybe the monster will leave but that didn't work obviously.
So then I was like, maybe that empty path isn't just a glitch or unfinished path, maybe I have to use it somehow and then I noticed the book hint about finishing the round and following the rules. So when I went to turn on the switch to remove the electric field, I noticed that one of the black figures disappeared but the other one was still around and that when it clicked, I knew what I had to do.
