If some rock mounds or trees or some other details are added to the OW's then it would help, but I think that your level designs should be good enough to still make this a good hack. I think a supporter bar is needed for this hack.
Your OW designs would suggest 6 worlds, not 4. Is it just me or have you changed it to 6 worlds?
Yeah when I said that I was planning on making this simply a 4 world hack but then I later added an ice area to world 2 so it ended up taking up two submaps and then I later decided to add a special world so now it uses 6 submaps instead of only 4 like I had originally planned.
