User blog:Sam Wang/BTD5 - Tips For Reaching High Rounds

Does anybody have ideas for reaching high levels (200+), since I always seem to game over at around 150 with many temples, possibly because of the lack of money. Recently, I found the way to gain money for early levels (1~100), but I start to struggle for money a bit when the rounds start to go into the 130s. By that time there are not enough space for banana farms, and 0/4 snipers aren't much affordable, so are there any better ways of getting to higher rounds?
