Great game, although there are two things which I agree on other people with. One is the page system, which makes long songs impossible as you have to make them in parts and even then, there aren't enough song spaces. Secondly, add some kind of highest rated for a certain time period, otherwise it's the same old songs over and over again and nothing new can get to the top.
Great game :D Unfortunately, there are a few glitches. For example, sometimes, after you kill all the monsters on a level, the game decides you are out of ammo and have to do it again.
Oh dear, do you remember what you/she said? I can add it in for you. (send me a pm or a bug report)
