I love this game. But I wish there was a freeplay where you could just keep going on a certain level. It would also be awesome if I could make my own track. And play other peoples that they made.
To beat the Motherships level, you need to have alot of batteries. I used a very simple plan, actualy. I had four solar stations, to the left of them were five batteries, to the left of them were three repair systems (crucial), and lastly to the very right there were only five THEL lasers, don't use missles they use up all of your minerals, they are next to useless. Everything on here was fully upgraded
