Could use some controls and directions help, but I figured it out and enjoyed the concept!  Nice animations and tradeoff between growing and becoming a bigger target.  

im not sure what i was supposed to do to get points to upgrade things. also wouldve been nice to get an indicator of how the missiles were going to be influenced.

Not entirely sure what the goal is, managed to kill a couple of other planets until I got blown up on my own. Would benefit from some instructions!
