Congratulations! Once again you stole a scenario, this time it is "Music Maker" from PiRocks. You should at least give him credits in your scenario description <.<

Excuse me, but I do not want my codes to be public. If you are interested in the behavior of my turrets, I can send you the parts of the code you are interested in.

I like the game but let me give you a little hint: If you make the images for your explosion static, they won't cause the game to freeze every time one enemy explodes ;)!
