This is a great game.
The idea is really original, although I've seen it elsewhere once or twice before. I loved the graphics, and all of the different themes were cool. I liked how it started with a random theme each time you played the game. It was very challenging, especially after 25. I was able to get in the 30s, amazingly.
It's also cool that you have a sound test. Is there a secret theme? Or did you put the last song in there just for the hey of it? Well, either way, this game is absolutely amazing. I played it quite a few times, and had fun, fun, and more fun. I love all your stuff. I hope to see more from you soon!
