For those who need 175,000 points, sending tons of pirate waves early will get that point total FOR SURE (I think 5-10 waves at once. Hope you have some good defenses.)

Perfume is probably the best block there is. If you put a wall of them, hardly any demon will be able to go through. Put two walls of perfume facing each othe and an om nom block in the middle, anything not a boss or fat will probably die in the perfume. OF DEATH >:(
Easy way to get long and big combos fast: Buzz saws should cover the everything but the edges (so turtles can bounce at the top) springs to keep turtles from stopping, and mines to spread increase the amount of turtles flying around.
You can use spells before a wave by pressing the spell's hokey when it says how powerful the towers are. Though, you'd only use the stun spell since it's the only one that actually works without minions on the field.
