Nice take on the revolution theme. Ah why didn't I think of this. The only thing that could have been better was making the UI like less cluttered. other than that it was really nice. Maybe more enemy types would have been nicer as well. Something like enemies that ram forward then move back. Maybe even make enemies change their orbit size like go into inner rings or move into outer rings. Really like it though. Can't believe its your first game jam. Good job :D
