Click the plant you are on to advance to the next plant, and then to the next, and so on. Craft new axes. When you craft an axe, you waste a diamond. Crafting can make a stronger axe or a weaker axe. Your axe will not be switched out if it is weaker. When ever you mine a plant you have a chance of finding a diamond, and you can upgrade that chance up to 99 times in the shop. Auto damage will do 1/4 of your power to the plant.
