I guess at steam you got a bigger audience of potential buyers for the game. The mass "one-time"-selling overweight monthly fee via Patreon / Subscribestar.
I prefer defently to earn the gallery. But i like to have the option to unlock all. Espacaily on game with mutiple path. I like to look up what i missed and don´t want to alter my gamesave.
I have to say, pretty disapointing. Waiting so long and now the hole game get a rework? So it will be more than a year until it´s on the content level where it was. And also until than probaly no new content.
