Garden Defense Zombie Siege

Introduction Garden Defense - Zombie Siege is a limited-shooting defense game with 2D cartoon animations. You can control a cannon to protect the garden from zombies at each level. You only need to control the crosshair with one button. All of the zombies will appear from 2 sides of the gate. I strongly suggest you shoot down the closest targets first than others. Although you have 3 hearts to start, you can only admit 2 hits from zombies.
