the ridiculously easy strategy:
Build a piercing tower with a booster on top of it on the far right. When you get 3 souls flip that stack and put a sticky block on the far left, then two squares right of the left, and stand in the middle of that. Stick a wood block and two cannons on top of the pierce stack and do nothing. For later levels swap the wood block with the booster and put a digestion block on the bottom. Use eye blocks and replace blocks as needed.
! is the hero.
