I downloaded it for the VC today, and so far, just past level 2, it's pretty fun. It's not as hard as LoZ, AoL, or SMB, or perhaps even SMW, which is good, but it definetly feels a bit more challenging than Kirby 64(the only other Kirby game I'vge played), but maybe that's because I'm just not as good as controlling Kirby with the Wiimote rather than the N64 controller. But it's fun.
However, I have a question to ask: Does this game automaticaly save? I would suppose so, since you get to make a file at the title screen, but just to be safe I left through the HOME menu, because nowhere did I get any sort of message or notice that it was saving. And trying to get past Metaknight's soldiers again would be painful.
Also, what do you think of this game?
