Harvest Moon: A Wonderful Life Special Edition

This mini-game is locked until you you reach Chapter 2. Starting with Chapter 2, Galen will live on the small hill below Vesta's Farm. In order to play the mini game, talk to Galen when he leaves his house around 6AM.

You'll get 60 seconds to clean Nina's grave by pressing the button. Unlike the Milk Drinking Contest, it's not about pressing as fast as you can though because you'll quickly run out of stamina if you do. Try and find a rythm that allows you to be both quick and efficient. 60 seconds is plenty.
