Don't Invest in it to much.
The idea of a "music video game" seems good in theory but it doesn't work well, biggest problum I see is to get the right mood(s) of the muisc to work with what the player is doing without restricting game play too much.
Biggest problum I had was I hit the explosion then the game/music stopped and I thought that was the whole thing when I did it again I noticed I could see the second tower(yes I got the girls balloon) but then I go too far and the game ends again which ruins the music.
Also 9/11 not the best theme for a first time.
