Alien Invasion: Tower Defense

Aliens are trying to invade! 

Gather your turrets and destroy them to protect the world!

Tower defense game with 3 levels, 7 different turrets, and 5 types of enemies. Each round gets harder, with the enemies getting faster, tankier, and spawning more often. Each turret has upgrades which makes them stronger. 

I would love to hear your thoughts on the game! Any improvements I can add, bugs encountered, or just your opinion on the game is greatly appreciated!
