Okay, the map pack has been updated. All tilesets have been improved with the following bug fixes:
~Tile patterns "stage.6-1" through "stage.2-2" have been changed to "low wall" to allow projectiles to pass through them.
~Tilesets have the addition of "shadow" tiles to allow placing aesthetic darkened shadows on the floors below raised platforms. Basically to show depth between floors.
~Within the tileset images, the hole corners "hole.corner_reverse.1" through "hole.corner_reverse.4" have been visually improved and now look better.

Thank you to those who noticed these bugs!! Please be sure to update your tilesets accordingly. These can be downloaded via the entire map pack, or individually from my site on the tilesets page.
Happy Mapping!
