-Point with your MOUSE to aim the plants. Once a wave starts, the plants will automatically start firing. -Press SPACE to place a marker for your plants to shoot at. -You can UPGRADE your plants by clicking on them, and then clicking the box, if you have enough cash to do so. (You can click outside the box to close it after it opens) -You can also SELL a plant from the upgrade menu. (It will only return the amount of sun you spent to buy the plants) -Each wave gets progressively harder, along with different zombies that will start spawning after a certain number of rounds.
The zombies have decided to NOT attack the plants, instead run past them. You play as a sunflower, trying to stop zombies from reaching your house. Sadly, there's only 5 seed packets left. Use them wisely. credit to the original creator, shadowspear1
