ahh, I have a soft spot for tower defense games :) the game introduction is really nice, with all the scenery "popping" up from the grass. And I enjoyed the music. After walling off my house and placing two turrets, the game was kinda easy, but I still had fun with it :) I could imagine, it's hard to balance the difficulty on a game like this with the economy and all. Is this the first tower-defense like game, you've made?
