Featuring a fresh set of vivid, newly themed worlds, The Rainbow Realms is a complete 8 world makeover, with level design aimed to keep in line with the style and creativity of the original SMB3. The difficulty curve is aimed at the average to good player of SMB3, though there are some challenging levels and a couple of difficult puzzles in the last few worlds.
