Hey guys, just finished my first android app. It's a Tower Defense game with role playing and sci fi elements. It's free, so I hope you guys install it and rate to support! I'm also looking for feedback and have made a thread in the appropriate forum for that, so if you have any comments or suggestions, the other thread is the way to go. Was a bit of a lurker while programming this app here and in the Andengine forums, so thanks to both of the communities!

Screenshots below. I had to resize them, hope I didn't make them too blurry.
