=> Use Full screen to look at the map better. => There are two layers, but it would be a better idea to make three if needed so you have the ground, walls, and roof separated. => The Purple Capsules are simple just placeholders for the player if it were to stand in the certain place. For instance, if the player was under a roof, as shown with two examples, then part of the player would be cut off to give the illusion of depth.
:) I entered a contest. This is not final as I will add more later if needed.
