Anyone know which files to extract to get the soundtrack music from the game?

Try to google Riveal , this tool could help you. :)

Thanks I ultimately did figure out how to get to the music. Unfortunately its not exactly the most usefable as much of it distorted with loud ambient background sound effects. Too bad that they never released the music by itself.

I wait for a Soundtrack-Release of this game, too. But with Paypal-Option. The Main Page of Presto Studios seems to accept only credit-cards.
