Also, get about 3-4 Saboteurs (x-4 Ninjas). They will be vital in the late game.

Priority (not in order): Sabotage Supply Lines, Ground Zero, Cripple MOAB, Bloon Impact, Sun God, BRF, Spac: Mines AND Storm.

In fact, research EVERYTHING. Tier 4 upgrades are so pivotal in the right circumstances that to make the best out of CT, you might as well save up for ALL of them. As this is a sim game, you can't expect good results in the short run unless you play for several hours a day.

Also, just look at the image I posted a long time ago. Other than bloonstone speed and supermicro, there was almost nothing I could do.
