[21:23] <Reid> I can't say you are wrong
[21:23] <Reid> although, post what you said on the forum, it's stupid to say it but apparently tmw forget about it on most of their map
[21:23] <Reid> evol does sometimes too
Many cave maps on tmw look like that. there is no way to figure out the height of the cave. Another example, this time I didn't use a real game example, but you get the idea:
Like i said, it lacks depth. In my opinion every indoor (whether it is a cave, sewer, or a house) map should have at least 1 black tile every x tiles, so that a player always can figure out how high (or low) the ceiling is. This can be done by adding a little bit of wall sections, pillars, etc. For future tilesets it might be a good idea to add some extra tiles that are able to give the map depth. Think pillars, but also variations for the north-south wall tiles (so that it is not a straight line anymore), etc.
