Exterior Roof for Buildings
When a player is outside of any building's interior, the interface should not present the interior of those buildings. Instead, the buildings' roof must be displayed which covers the interior of that building. This is similar to how buildings look like in Stardew Valley. The design or style of the roof can be generic and/or randomized for the meantime until a system is set in place for choosing the roof's design.
If the player enters the building, then the roof of that building will disappear, and the interior of that building will be displayed instead. This suggestion is purely on the front-end side of the game.
