Full PC Version is available on steam, but not here.
I don't fuck with Steam (I have my reasons), so that doesn't help. And even if I did, I'd still have to pay the $15, all over again.
If you want the full version without going through Steam, you still have the Backer version; you may access it by subscribing to the Mature Dragon tier ($5/month) on SubscribeStar or for free if you contribute to the translations of the game.
