Tips:
Since you already have a Monkey Village built, consider placing towers within its range to take advantage of its effects and cost discounts. Start by building an Engineer in the southeast and upgrade it to 2-1 at least.
After earning enough cash, deploy another 2-1 Engineer in the NW and from there, you can add the towers you prefer. In my game, I added Bloonchippers to help delaying the bloons. As you progress in the later rounds, adding a Super Monkey is a must, preferably in the middle of the map.
You have to balance out the tower placements along both paths to ensure that nothing leaks past your defenses. Once the MOABs start to appear, deploy MOAB Maulers near the bloon spawn points to destroy them as soon as possible.
