Really well done. The interface is very confusing, and will turn people off before they get a chance to try it out. The gameplay and upgrade system is great though!
Really well done for a first game! I like the concept! However, I don't like how you can collide with your turret, and that it disappears when an enemy hits it. It would also be nice if the turret tracked enemies instead of shooting in a circle. Other than that, great job!
