I'm just fully completing the game. If you never see the Game Over screen then have you really seen everything the game has to offer? If the developers didn't want you to have a Game Over then they wouldn't have put it in the game.
I'm just making sure you get the full experience of the game and don't miss out on anything.
Moreover, you make it seem like getting a Game Over in Kirby is a hard thing to do. Yet, despite the challenge, I accomplished that so obviously I'm a better gamer than the majority of players because I can pull off this feat. If anything, my title should be Top Ace Nintendo Gamer Loyalist. T.A.N.G.L. for short because no one else wants to tangle against me in a competitive Nintendo game.
