Medivo...

*Bad Masking
*Bad Tile Placement
*Background isn't big enough to be used as a Textured BG
*Pointless tile 8,28
*Pointless tile 7,34
*Tiles 7,54 and 8,54 aren't masked
*Random pink tiles?????
*No opposite version of tiles 6,84, 7,84 and 8,84
*The bee-hive is masked
*Text and exit signs can't be used against the cave tiles
*No key block or text sign in Medivo 2

And this list only has a few bugs, there are WAY more in that tileset.

So I'll fix this.
