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 just want to let you know, don't feel discouraged because your hack hasn't been moderated yet. I've been checking in on the unmoderated hacks every so often, in fact I submitted two *incredibly dumb* hacks and they both got accepted on technicalities, so I feel your pain about your hack not being moderated yet. This is an excellent hack, and you are an excellent hacker. Hopefully it'll get accepted soon, but for now, keep on keeping on <3
