it kicks ass!

loved it and beat it

The graphics are nice, especially the backgrounds which is really rare in Tower Defense games. The enemies are also very distinct and charming.
The sounds are good and the monster voices pretty amusing although they could easily have had been more varied (each monster had four lines each?) and bosses could have had unique lines. I am missing some sort of optional background music (I didn't find any) though, as it tends to get rather silent the times you're too lazy to fire up iTunes or Winamp.
The gameplay is fun and the towers are well varied. The only one I didn't find very useful was the fire/splinter towers which I didn't even try for very long. I'm not sure if enemies can be frozen/on fire at the same time, I haven't tried, but even if they can the tower still feels pretty useless.
Some upgrades also seem very useless, such as I think it's the third level of one of the blue towers - a two meter range upgrade and nothing else. Upgrading rarely really feels worth it, unlike many other TD's.
So what I'd like to see in the next would be blended rounds, with several different kinds of creeps attacking at once. Many other TD's have them and it usually adds another level to the gameplay.
Some more maps would also be great, especially a feature to create your own maps.
Very amusing Tower Defense though and the difficulty is pretty OK. My first time on Easy I beat the game and only missed like 5-10 enemies, the second time like 20-30 (bad tower setup), playing on Normal I got to 47.

This is the first Elemental tower defence that was actually doable. I can easily say, that this is the game, which happens to be better then its older version. I like how you can regain those Elements back. I only did one playthrough and i got to about level 45. i think that is a good spot. After that i quited. Just because i noticed that my setup wont take me any farther. I think of redoing and having the setup better. Nice game. Rated 10 out of 10. It's obvious, for this strong game.

one of my favorite tower defense games!
