Rethink the bosses. Space penguins? Not only ridiculous but also it is strange how fast they appear after you send the signal, they should just spawn from time to time like the bosses of Terreria after you activete the signal. Also, that robot, you need to make it, so you can defeat it and grab a processor. But if you made the entire robot (and that excuse for it going crazy, don't explain why you know how make it, or you decide to do that), couldn't you build the processor alone too, since it is a drop of the robot that you built? Also I thought that could be nice if the bosses could spawn without you near and attack your colonies (the ones you spawned people), so you would need to hurry and back there to defend it. You could also make some defense turrets to help defend the colonies while you are away (giving you more time to arrive there).
