Seed tells, through its FPS game structure, the vain and desperate attempt of a farmer to block the growth of his only lily.

The purity of the flower is constantly threatened by the incursions of bats, ferrets and doves, who want to take possession of its lifeblood.

The game develops like a tower defense in waves: in the center of a floor there is a large lily in a flowerbed, which the farmer must defend during the waves from enemies arriving from all directions. Between one wave and another the farmer can buy power-ups in a shop.
