Sometimes this game's dialogue cracks me up. Archfin Lord - "There are no words for what you have done." Lethal - "Murder, kill, death. There are plenty of words for what I've done - it's not that hard!"
I always relocate my minions to the moon right before the final mission...guilt I suppose. :P Even though I have no issues with sacrificing the failures beforehand.
Enough MP to use Rampage 3x in a row is pretty much an "I Win" button for regular enemies...and Silence at the beginning of every round accompanied by Regeneration is the "I Win" button for the bosses. :)
I got gold on every level using the following strategy. Put a column of piercing blocks each facing towards the middle. On the bottom of each column put one of the blocks that increases the damage of all the blocks it is stacked with. Between the columns you can put any block you want (two eye blocks in the middle between them is enough to see all ghosts - otherwise I used cursed or magma blocks.) On survival first put one column of digestion blocks facing the toys right next to the toys. Put a column of boosted cannons facing towards the portal next to those and right next to the portal put another row of boosted cannons facing the toys. Then put two eye blocks in the middle again to see Envy. As long as you replace the cheesed blocks right away you should have no problems! ^^ NOTE: On the gluttony levels put your piercing blocks on the bottom and the booster on the top to kill gas demons.
