Wario rando 2: nusumareta zaihô

Ok. This will make me sound a bit feeble, but although you are invincible, Wario Land 2 is actually strangely hard. More than just avoiding enemy attacks/killing them, there is much more "state changes," for example, the chef's food makes him fat(ter), if he's stung by a wasp his face puffs up and he floats away, all giving you new abilities. And then wheen you complete it, there's lots more levels to find. Admittedly, I haven't got any of them, but who's to care? It's a pretty worthwhile purchase.
