I could definitely see this in a game.
A bit loud for my tastes, obviously, but I can tell it's well done for what it's supposed to be. Personally though, methinks this'd fare just a tad better if it were a loop. The end just felt like it was put there for no reason other than to stop the music.
You have no idea how right you are. If there's one thing I can't do properly, it's kill the music properly.
Thanks for the review!
