I'm not a big fan of tower defense games, but this one was great for what it was.. I wonder if it'd be possible to make a sequel where you were the one on the side of the waves.. that is to say, a tower OFFENSE game. It might be interesting.. to play as a general in charge of a horde of cannonfodder. Just a thought.
Seems like it'd be a fun game, if not for the painfully slow load times and general lag. As it is, it takes my character about a minute to get from one side of the screen to the other.. and I don't have the patience to put up with that.
