"Trolley Problem" is an action-puzzle game set in a world made up of hundreds of countries. Players make full use of the rich gimmicks and brains of each country to guide the main character Lily, who manipulates a magical trolley, and deliver the "fruit of heart" to the people of the town.
Will you run over the residents and deliver the fruit to the town without damaging it? Will you accept the risk of spoiling the fruit and deliver it to the town without getting your hands dirty? Or, any other else choice?
The story moves in different directions, depending on the player's guidance.
