The game will be Early Access which means it won't be complete. We still have a ton of work to do, but this gives people the chance to support us without a subscription. The Early Access version will receive regular free updates until the game is complete.
Also, the Early Access Steam version will have a launch discount of 15% for a week which will make it about $11 instead of $13.
Since the game is coming to Steam, I, as an active Steam user, are interested in two questions. Will there be achievements Steam? This question worries me a lot. If there are no achievements, then the game becomes less valuable in my eyes. And the second question is whether there will be Steam collectible cards? This is not very important, but will not be superfluous for the Steam game. I think you don’t need to ask about Steam save synchronization. Every game should have this option...
We do plan to add Steam achievements in the future. Right now we are focused on the main mechanics of the game. As for collectible cards, I'm not sure if Steam allows adult games to have collectable cards (I need to look into that.)
Right now we are working on save synchronization. We hope to have that done before the launch.
