The videos feature really awesome music... I wonder why the soundtrack of this game isn't available, not even as separate DLC?

Second that, it would be nice to have and devs deserve few more coins for all those dune references.

The soundtrack is on bandcamp

As a person fiending for anything and everything synthwave, this was an instabuy.

Thanks for finding this out!

No worries mate!
Shameless plug; If you want a whole lot of similar themed music, take a look at my bandcamp collection. https://www.bandcamp.com/devjock I've curated it in such a way that it's approachable to both decade long veterans, and newcomers expanding their musical horizon. It's roughly centered around electronic ambient, high profile vaporwave, rare edm, the occasional weird sprinkle of oddness, and a metric ton of synthwave from all over the globe.

As the synthwave scene is still quite small, basically everyone from promoters, reviewers, artists (both music and coverart), remixers and fans are on twitter, playfully taking the piss out of eachother, collaborating, remixing, seeking further fringe genres we can meld together with, and doing a whole lotta #followfriday's Soundcloud also has a very active community, everywhere from first releases (subsequent releases often go straight to bandcamp, as it's the easiest platform to support the artists) to full on weekly release podcasts with fantastic production quality (and maximum shenanigans).

The soundtrack is indeed available on other platforms (bandcamp, etc.), but we are in discussion with GOG to provide it here also.

Thank you! Also thank you for being present on these forums as well, not all devs do this! I'm LOVING your game so far!

You're welcome

Oh my goodness, thank you!! I love this game and the soundtrack is fantastic, so it'll be a definite buy from me, too. :D
While I'm at it, I'd like to say thanks to your team for all your hard work. You guys have made a work of art.

By the way, you can get in contact with GOG to get developer status on the forums. It turns your text orange and lets people know you're the real deal.

Thank you very much for your kind words. Means a lot.

And thank you for the forums advice. Will do.

Still no luck bringing the soundtrack here? ;_;
There's also the neat artbook DLC available on Steam but not GOG, too... Gah, I want to give you guys more of my money!

Oh no, that's unfortunate about the soundtrack! Well, thanks for answering anyway.
I've already bought the OST on Bandcamp, but I wanted to support you here again because it's so good. :'D

Getting the artbook here would be amazing though! Fingers crossed
