I learned what kind of strategy to use on another tower defense game that utilizes accumulating interest. Here are a few tips:

1) Save as much money as possible by just building what you need and nothing more. You want to just barely beat each level.

2) Because your interest accumulates when each level begins, first send the next wave, then while they are approaching build what you need to defeat them.

3) Use ALL bonus upgrades to increase your interest. It will pay off when, at the end of the game you’re getting 30% interest each round.

If you do all these things you will gain far more money through interest than through killing enemies and you’ll easily have what you need to defeat the level. Plus, the more money you earn the higher your score.

Did I mention I’m totally addicted to tower defense games now?
