Coming out of Barry's room, less than 100 steps from V's place:View attachment 11161874
If you use double jump to see what is one floor below you get an auto flatline.
Go exploring they said. It'll be fun they said. You can't even join the cops talk in Barry's room because of an invisible wall. No "Please leave us alone!", no reaction at all. Just an invisible wall right next to the auto flatline area. Rest of exploring was not better. This is no open world by a long shot.
There are far too many "Step out of bounds and insta-die" areas, some without any warning or making any logical sense.
