A Tower defense game I guess

This game really had no name. It never got that far. It was a joint effort between my little brother and me. He did the art work and had a vision and I made it come to life using the programming. I spent about 3 hours last night putting it all back together and fixing long time bug fixes. Here are some screen shots and its not much to look at. It does however have all the systems needed for a tower defense game besides an upgrade tree. I will continue working on it for the next couple days on and off and post an update every three to four days. Feel free to download and play it. Thank you and have a great day!
