Hi there, thank you! You can get access to the full version by backing us on SubscribeStar. If you back us at $20+, even for just one month, you can also get a permanent Steam key that you can redeem in any region. Steam blocks sales in some countries, but not key redemptions!
In future we would also like to make the game available on other storefronts, but there's some technical and legal hurdles to sort out first.
