I seem to be having trouble with the very last wave. I am on normal mode and I cant gather enough food for when the enemy colonies come. Also are aphids worth it, to me, they're more trouble than its worth. It's like the ladybugs are just Circling around the beach, I expect there should be some breathing air before the next 1 comes. I started to ignore the aphids and get the wevils that come out at night. Is there any previous post that can answer these questions?
