19103400 final score (game final score = 58799) I am sad because after maxing out the zombies, it is literally impossible to not destroy a town, even if you only click 1 time or use only 1 special zombie instead.
for level 34:
rotate the L-shaped piece until it is like a slanted to the right upside down L.
_
(a | shape, but slightly leaning ->)
place it on the left part of the circle somewhat close to the center. Drop the line piece on top of it for a slightly -> platform. Rotate the + to a x and put it on the right side. It should BARELY lean back onto the platform without it falling off. Finally, put the 3 circles to the left of the x. For a picture:
