The music is just an "elevator music" instrumental-only version of the Violent Femmes song Blister in the Sun. If you're thinking the music sounded familiar but couldn't quite place it, that's the exact song. Go ahead and look it up on youtube if you're unfamiliar with that song. I'm right.
Shame credit was not given anywhere I can find. And, no, the person who was credited with the music in-game is not the Violent Femmes but good job making an "elevator music" version of their song without crediting them I guess, lol. I hope you had permission to cover their song.
As for the game itself, the graphics are nice but the gameplay is boring and just too random.
Also I'm kind of surprised no one else figured out the song was not original and which song it was a cover of.
