Now that I've played through the game...
This is one brilliant soundtrack. The tracks have a lot of charm to them, and are clearly very well-written. (I think it's better than Recettear's!)
If it's piracy they're concerned about they should note that fans will get to it anyway, such as that youtube playlist posted earlier. It's much better if they give fans (like myself) who are willing to throw money at them the opportunity to throw money at them and get maybe a spiffy set of MP3s in return.
I wonder when the next Game Music Bundle is coming up. Perhaps it could be featured there.
La-Mulana's soundtrack (and the game too) were featured in the Groupees "Build a Greenlight Bundle". Maybe CF and LizSoft could look at how NIGORO is doing with their soundtrack sales. (NIGORO also put La-Mulana's OST on bandcamp, I think.)
^^ That track could simply be renamed. And I lol'd when that track came on too.
