Well, I'm 'bout to give up. I've retried this level about eight times, I can't seem to manage to hit the homing circles now that my shots split into a V. That and they tend to just hide under the bits and hit me before I see them.
I actually would NOT recommend buying a crapload of quantum pillars. I have a bunch of Gravity creatures, and on average, even with like, 6 quantum pillars I get maybe 2-3 gravity quantum per turn. Which means, I can't use ANY cards
