IF YOU RUN SOME DISTRO OF LINUX AND CAN'T GET THE GAME TO RUN FEEL FREE TO EMAIL ME AND I'LL SEND YOU A STANDALONE SWF VERSION . working on solutions for other distros but this game does use adobe air which is prone to problems...and I'm admittedly not the best cross-platform programmer etc
Steam Keys: I can't generate these yet and am e-mailing Valve to see when I'll be able to. You will get a Steam key somehow if you bought it before this point in time. For now, patience!
If you bought through Humble Store, Steam (and GOG probably) keys will pop up in your purchase page.
If you bought BMT/Fastspring, you should already have gotten a Desura Key, anyone with a Desura version can visit https://secure.desura.com/cart/cdkeys
in the future and the Steam key should be there.
Still working on good ways to get keys to GamersGate/GOG/elsewhere. If you want one fast just e-mail me.
OST: If you like the music feel free to buy it here http://seagaia.bandcamp.com/
. I can't put it as an optional DLC for the game because Valve is moving away from that, so here's a 40% discount code for my bandcamp: steamparty .
