A simple idea, with a nice RTS set up. I ran into some audio issues where the music clipped out whenever any kind of ship shot any other kind of ship. I did enjoy the feel of 'numbers go up', where eventually I had enough energy production and mass production to upgrade energy and mass for practically free. The game overall was quite easy, but I don't feel as if that's necessarily a bad thing. I never figurered out how or if you could control where your ships went. They all somewhat just moved to one spot and basically became an island of guns, and I never really got any feed back on my production facility's health. I assume that if that gets destroyed I lose. If it was part of the UI I recommend increasing it in size and making it more prominent, adding a bit of feedback each time you lose (or potentially gain health).
