Wallpaper UFOs

This is a live wallpaper featuring two teams of UFOs battling in short matches. When the wallpaper is installed, all UFOs are identical, but as they fight they'll evolve new strengths, weaknesses and a personality. Some will keep a safe distance from the weakest enemy while lobbing shots at it. Some might bull rush straight into the nearest enemy and some might just sit and wait for the enemy to come to them.

I've always liked games that kind of play them selves. The ones where you build and build and suddenly whatever you built is self sustaining and plays it self. So, I decided to create a game that I don't have to play at all.
This is a spare time project that I have spent a couple of weekends on. I did it because I wanted it and I'm publishing it in case someone else likes it. There is no advertising or other monetizing on this.

The sum of all the UFO properties is constant so there are no super-soldiers. If a UFO have very strong short attack, it needs to be weak on something else.

Thanks to Emmy Lincoln for drawing the UFO and ustwo for letting me use their color picker and time.
