Get a boomerang in the corner of the middle square, it will serve as your basic defense, give it couple of upgrades to your liking while either focusing on a tack turret(4 I 0) in one of the corner or a boat in the pond(Aircraft)

Your boat will be able to score massive damage of damage. Your tack turrets, once upgraded, will just beat up the bloons as they slow to cross the corners. Get one more in the remaining corner. You could put two side by side at the start of the track to soften the bloons.

After that, you just place what you want, following the above will kill a ton load of bloons.
