Try to NLL tiles that you capture. If you lose a life within the first 5 rounds, restart the tile and try to obtain the 5 bloonstones you get for NLLing the level. Also, try not to spend them that much, as they are very helpful (and required for tier 3 and path 2 tier 4 upgrades) later on in the game (believe me, I only have around 200 bloonstones now, and I am level 22).
