I honestly don't know.
I don't know why you people are Q_Q'ing so much. This game is great, and it works well, for such a small size. Sure, everything is hard to deal with, turrets and all, but later on, it gets good, and everything comes into place. And you have to really upgrade every part of the drones, to seriously get them to work... And they repair when you AREN'T being attacked, if you haven't noticed. 5/5, and 9/10, since I think that you could atleast earn credits (Or "RU" as they're called) faster, and in more amounts, and a few other features could be implemented.
The style of the ships were nice, although, I don't like the ships you have. They looked like thin, dead carrots in my view, to be honest. Something bigger, is all I'd ask. And the ships themselves weren't of a clear quality. They look like they were done in MS paint. That's another thing to work on.
All in all, good job.
