Well, I have some characteristics that I remember.
(Maybe I'm right.)
1:I remember it had many levels and an online mode.
2:In online mode, you defended and accumulated points to send stronger troop attacks against the opposing player.
3:You don't upgrade towers with points accumulated in the match; you only use variants of the same tower, just stronger and with different designs.
4:I remember there were many variations of the same tower, with different designers and many different enemies as well.
