Did you enjoy the old Mario games, but tired of them because they're so easy? Then it's time to try a polar opposite. Here are a couple rather famous hacks of the classic SMB and SMW games, that were designed specifically to make your life difficult. The level design is nothing short of ingenius, if not hilariously cruel.

You can download all three of them here:
