If you are struggling HERE is a guide you can check out to help. Some quick tips are that it can hear your footsteps, will use sound to track you, and can see the light from your flashlight. Be incredibly cautious when it is close by or use your fast sliding movement to create openings for yourself.
I'm sneaking around without a light. I'm using shortcuts, but the monster is definitely heading towards me. It's not looking for me randomly. I hear his quickening footsteps as I leave the shelter, because he knows when to attack. All things considered, it's a good game. The only downside to a hide-and-seek game is that you can't sneak normally. I think we need to give the monster a conscious zone. So that it's close but doesn't know exactly where to go.
