Hi. During a shootout on the red floor, it is easy to lose sight of the opening in the wall when the room is quite intricate or cramped. Sometimes this is critical during a retreat. I think it's possible to paint the doorways at this location light orange. It's a small detail, but it would make the floor a little better. In general, many places can be made more understandable by using a more active color indication. Despite the fact that the setting is technological, largely industrial, live players still need it.
