Symbiosis is a unique strategy game that pits plants against crystals! Grow plants and use them to destroy all of the crystals on the playing field. The closer a plant is to a crystal, the faster it will attack. Increase the growth speed, attack power, or defense of a plant by switching its state. You can also increase a plant's attack or defense by transferring energy to it from another plant. A plant can't grow or attack while it is transferring energy to another. Throughout your campaign, you will earn points that you can use to learn skills and spells.
