a tip for the last level on gold: use 2x goblin,healer,cleanser,shield, 2x goblin,healer,cleanser,shield,elemental,goblin. then keep the front goblin alive for at least 3 turns. use stun on the first and second nuke tower and use quake on all the towers in the top right with the right timing. after it costs too much to use 2 stuns, switch to stunning the first nuke tower and using quake on the last 2 while also getting some of the towers in the top right. thats how i got all golds.
