Go to the shop and click on the plant you want to buy, and it will follow your mouse pointer. Use the arrow keys to turn it so it faces the direction you want it to shoot, then click on the spot you want to plant it. You can't plant on the path (Which is tan). Click on the start wave button when you are ready. Zombies will start spawning and the plants will attack. You cannot buy plants until the wave ends. If a zombie reaches the exit, you lose a life. If you lose all of your lives, then the zombies eat your brain, and you lose.
Note: the game won't work if you place more than 7 of the same towers. (The zombies won't spawn, and the plants don't shoot) Expect future updates! Next update: wall-nut and pole-vaulting zombie.
