Harvest Moon DS: Sunshine Islands is a farming simulation game for the Nintendo DS, structured around four seasons each lasting 30 in-game days. Players cultivate crops, raise livestock, and engage with village residents. Unlike its predecessor, this title offers traditional button controls alongside touchscreen options for character interaction and movement, enhancing gameplay flexibility.
Gameplay is split into four 30-day seasons to make up a year. Each day takes place over approximately fifteen minutes.
Unlike its predecessor, Harvest Moon DS: Island of Happiness, the player is not limited to controlling the game with the touch screen. Speaking to other characters within the game is either activated by tapping the character or pressing in the A button while facing them. The B button can be held while directing your character to bring him or her to a run. Although the player can now use the buttons, the old touchscreen control system is still intact.
