You really need to synchronize the breeding timers for all breeders. It's annoying having the timers staggered, I can't click on the clovers I want to click on.
HOW TO BEAT LEVEL 16: You need a combination of the following tactics: deathstacking, and divide and conquer.
You expand to the first circle, and wait, building up a deathstack in that circle. The other two enemies will claim everything else, yes, but the majority of their ships will be used to fight each other.
When your deathstack reaches 150 ships or so, make a beeline for one of the x3 circles. If you take it, you're done. Taking the second x3 circle will be much easier, and then it's just mop-up.
Lightning Storm OP. After expanding as fast as I can until the fighting starts, I just make a couple of Wind Heroes, nuke every 3-square building down with Lightning Storm, and watch your enemies crumple before you!
I think the screen "Lifts and Spikes" is almost completely unsolvable on the bottom. You cannot get on the lifts from the right, except by glitching through the lift platform.
