I'm considering raising the elevation for buildings by a tile. This should eliminate that problem and making other buildings appear taller.

As far as the pallette, map tiles and characters have their own. This was done in the NES to make characters pop out on the map.

Reminds me of Ghostbusters 2 when they were in the photo room inspecting the river of slime. Looks well done though. :)

Ok...? Perhaps some details on its strangeness?
