Update: now with enemy health. This is my first tower defence game it has 6 differnt towers and 20 working levels i may or may not update this i hope you injoy it :) story:you have a castle. Two very cheap invaders are trying to invade it but when you almost kill them they will teleport out. Also because they are cheap they will only upgrade their armor if you defeat them in their current armor so it gets tougher. controls: if you can afford it click on a tower(do not drag)move your mouse where you want it to be built and click again. The current wave is displayed at the top right left of your money. to start a new wave of enemies. you earn 50 money when you force both invaders to retreat. your live counter is above your castle.
