SMB3: The Rainbow Realms

Hack of Super Mario Bros. 3

Featuring a fresh set of vivid, newly themed worlds, The Rainbow Realms is a complete 8 world hack, with level design aimed to emulate 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.
Good luck, and enjoy the exploration of this colourful collection of levels!
