Beat level 11 after 20 tries. Upgrade mini guns all the way...no elements. Put them at the u's and upsidedown u's and put cannon's with freeze right next to them. Upgrade those too and you're all set. 0 lives lost finally!
I appreciate the effort but the dice are totally loaded on the side of the defense. That makes it a lot less fun. Keep going though the next one will be better!
