Great game - great run, unfortunately the FPS where down to 0,3 and i couldn't dodge anymore.

The Tower-Pickers are arranged in a square use this as orientation
Close with teeth so that each side has two entries in the firing line of the skulls
Skulls and teeth to direct the enemies
prepare second wall
Close it after the queen and upgrade the outer wall with high teeth
Late Game build a zig-zag maze of skulls and an inner ring of eyes
GG
The last rounds where really lagging. One frame every few seconds. I was standing in the middle and let my maze do the job. Eventually one of the 16 queens summoned a unit in the middle as their shadows ignore walls. I saw it in one frame and was dead on the next one.
I added some tweaks that i didn't mention in my strategy (too keep the highscore). If you want to go further than that you need some serious juking, which i am already thinking about ;)
