Only one problem:
That being that if you fail, say, because you build a powerplant at the beginning of level two, instead of building as many turrets as possible, you have to start back at LEVEL ONE!
Allowing people to start back at level two would be nice.
So would battle sounds, too. I want to HEAR the "chatta chatta chatta" of my turrets whooping butt.
No Saving
The lack of a save/continue option so you don't have to start from the beginning if you loose dented your score dramatically. It was so annoying having to start over again so you could complete a single level.
Blah...
I liked this at first but then it got to the point where the game was trying to make me spend more money then i had. The waves where to big to fast! I got a few things going but then it all fell apart. This seriously need improvement.
I found a cheat
Press enter and you win the level
WTF
Iv played this game for a few years now. THE DAMN 2nd level is to hard!!!
