i played Vector TD and I used nearly the same tactics as I've used in Tower Defense 2007. During the game it looked good, I had much more money than needed.

Here is aSreenshot:

Round:_ 50
Lives: 15
Money: 366735$

Can someone give me a clue what I could doo better? I'm far away from 15 mio. I know how to make money, but how can I get more points?

Or isn't that much money for the last round and I have to earn much more to get more points?

Any help would be apreciated much.
