This game killed a whole day and in a good way! I was able to find all of the pocket items but not all the phone numbers, but I'm not ripping my hair out trying to find it all :)
A small bug: when I was on the roof I was able to get around the guard rails, and I fell into a part of the back of the building that I couldn't get out of. A quick restart of the game fixed it, but I panicked for a hot second, ha!
