simple and awesome
Very nice game, and it's wonderful that you pulled it off with so little in the way of graphics. It's the type of game that makes you think "hey I could've programmed that", and those are always the best. Innovative... genre-making, or, at the very least, within the tower defense genre, subgenre-making. Might be nice if there were an endless survival mode or something.
simply a wonderful game 10/10
