This is simply a list of bugs you may or may not be aware of.
1: map markers are far off. I could be inside an area and still not "discover" it.
2: on occasion, the reload will not register, confusing the player why they are not shooting.
3: some exit timers reset when you are hit.
4: some items can only be activated when facing it from a specific point and direction.
5: board mazes at the top a barnhouse knocks players off, leaving the visibly inaccessible.
