Aw, man! This is such a cool idea for a game! I love finding those rebel scum! Although, at the end my true allegiance was put into question because of my failure to find them all. XD
Only feedback I have is that it takes a little long to scan ships, which made the game feel like I didn't have enough time to really analyze them. But maybe scanning is supposed to be super powerful and risky to use and your main method of telling if they're scum is by checking their ion signature? Either way I love the idea of this game and you did a great job!
