Impressive
Okay, this is coming from someone that generally doesn't like Tower Defense games. I have to say, that I absolutely love this game. The idea is solid, using music notes and such. The design is cool and techno like, really appealing to my music senses with this list of songs.
However I have a couple problems, for one thing the notes sometimes don't appear at all. Literally I could wait waves and nothing would happen, and when something does happen all the enemies come at once and clobber my ass if I'm unprepared. For another thing the tower usage seems unbalanced. What I mean is half the time I can choose only one type of tower while the rest sit in the holding area, collecting dust......not a good thing. Especially Pink and Blue, I literally had no uses for those two towers all the way through. If you can make them they are useful, don't get me wrong but because of how expensive they are, especially blue with 70 bucks attached to it, it makes Blue completely useless.
Other then those couple things I absolutely adore this game, and I can't wait for more songs in the future.
