You goal in this awesome tower defense game with a twist is to kill all the insects in each level. Build your tree out and up and place weapons on the trunk and branches to fend off the invading insects. Your weapons will not fire on insects once they've landed on your tree's trunk, so spread out and place weapons with that in mind. Before each battle, upgrade and equip your plant weapons. Once you start the battle, upgrade the main tree to add branches and attach weapons to those branches. Use YOUR MOUSE to control the game. Scroll with the MOUSE WHEEL or use "Z" and "X" KEYS to zoom in and out. Drag with the mouse or use the ARROW KEYS to move the playing screen. Hit SPACEBAR to center the scene on the trunk. Have fun!
