Tip: You can use Lunar Magic's Overworld Layer 3 Editing system to edit or create your own layer 3 images (castle bricks, fish, rocks) and apply unique effects per level via the Layer 3 Bypass in the main editor.
I for one, think it looks okay, but I agree with Blue Cheese that it should probably have at least one
screenshot using the foreground tiles. Well, the last two (3 and 4) kinda gives an okay idea, but a screenshot
with some background (just background color would be enough) would look a bit better.
