-sample level can be viewed in the .mwl file,
-while the fog is detailed, it uses 7 palettes, so you must use the DKCR Sprite Status Bar patch.
-the BG does use 210 8x8 tiles.
-transparency is enabled for the layer 3 effect.
-every .mwl file has its layer 3 palette.
-.pal and .palmask files do exist for each palette variation.
