This is a very quick and very simple game I made to test some code, first uploaded on August 27, 2011, that I was working on to make a rotating object work. I was having lots of trouble with Android scaling my images as I rotated them due to the bounding box size change when a rectangle is rotated.
Eventually I thought of the method I use in this game but I didn't want to completely rewrite the app just yet so I made this as a test. I thought my rotating arm looked like a gun so I decided to make it shoot and add enemies as well as a score.
I think at some point I uploaded this elsewhere and said the source was public domain and if I didn't I am now.
