Nintendo has been in the business of making platformers for ages, so it's not surprising that any attempt to improve upon their existing products is set to end in tears. Still, that has not deterred amateur game makers from attempting as proven by Marioland Plus
The controls are awful, certain sound effects are missing, and sprites lack any sort of consistent quality. There are much better freeware platformers available elsewhere. Avoid.
