Previous games had them, this hasn´t. Does anybody know the reason for it?
I was surprised about it as well. Maybe this time the music artist has a bandcamp page where people are supposed to buy the soundtrack, and it’s separate from the game? I haven’t checked it, but I’ve seen that being the case for other games before. That would be one possible reason I could imagine.
A quick web search shows my suspicion was spot-on: Embedded Bandcamp page of Supergiant Games/Darren Korb is linked on the Supergiant website.
