Vector tower defence strategy game!

Village Defence is a fun strategy game where you have to protect your village from invaders by building defensive towers to destroy the enemy. Success is not based solely on the types of tower you select, but where you place them and what upgrade options you take. When you have eliminated the first wave you can build some more towers and/or upgrade existing ones. Select a map from the list, select difficulty level and play! A strangely addictive game... how long can you survive?
