Superb game! True, the only real challenging level is 9, but that's how its supposed to be.
Biggest problem is lack of resources in level nine, so you litterally need to mine the entire field, spreading out as you are attacked, because after the first wave of motherships, you wont have the chance to expand further.
I like to mix it up a bit, but don't underestimate the pure towers. A line of 5 at lvl 6 pretty much kill everything.
As for the special towers, splash slow paired with Teleport and big splash is always usefull.
I got a(n) Z... on hard! My score was 0 with a max combo of 0. I scored 0 perfects, 0 greats, and 0 goods. I got only 0 bads and 10 misses! I was playing on 15 speed and had 8 crazy options on. Great game, I like it! Play it here: http://www.thorgaming.com/games/3926/feel-the-beat.html
