Got the Piece of Heart on my first try doing only a mediocre job, but I'll agree the game is seriously flawed.
Why do Zelda minigames get worse and worse as the series goes on? Kina's Harp, Skydiving, Slicing Bamboo. Digging's fun even with how luck based it starts, but everything else I've played so far is not something I would do for fun like Wind Waker's or Ocarina's games.
