Is buying Patreon access a one-time thing, or do you need to stay subscribed? I wouldn't mind paying $30 or $40 for early access, but having to remain subbed is ehhh.
If you stop supporting us on Patreon you will still be able to play the version of the game you paid for forever. And you can reinstall it from the archives. But you won't be able to unlock the newer versions. And yes the goal is to release the game on steam when it's done.
