Tower defence is a spectacular defense game game where you need to protect the Princess by defending her tower from the relentless onslaught of enemies. To do this you must pick the enemy soldiers up and throw them off either side of the screen. To activate a power simply select the corresponding icon located at the top left corner of the game screen. Pick up the soldiers by dragging your mouse and click on the powerups on the top left side to activate them after their cooldown phase. Enjoy!
