Game: Dr. Robotnik's Mean Bean Machine

For a world famous doctor with an army of gigantic evil robots, Dr. Robotnik sure is cranky. That's why in Dr. Robotnik's Mean Bean Machine, the villain best known as Sonic the Hedgehog's arch-nemesis decides to kidnap a whole bunch of beans to turn them into evil little robots. Or something like that. Really, the goofy story is just an excuse for some addictive puzzle action. But while the main puzzle mechanic is fun, the difficulty level gets incredibly high very early on and the game also suffers from a frustratingly archaic password save system.
