so i haven't watched the vidoe yet, idk what you mean by "could catch me sometimes from half way across the house", if you mean detect you than that is how it supposed to be, yeah the map is unfair but the AI is easy to outsmart (for me and for some of my friends).
There are some good hiding spots, under the table (slows down detection speed), behind TV, and inside the cabinets in the kitchen (it's not indicated that you can open those), the garage is really hard and risky but has an amazing payoff, for me the AI bearly went in to the rooms, it's really person dependent, i am amazed how well Puppet combo does this, and i implemented the AI in 2 days.
All i could do is tweak the AI or add some walls? but idk how, because for me it seems okay, i will watch the video today. Thanks for playing.
