I mean this is pirate site, someone needs to leak the updates here or if the game is free updates needs to go Game Requests thread to ask the new update. If not then yes, there is PAYWALL but that really depends if someone leaks updates or not.Not exactly. Steam version has the most content, then Subribestar, then public (what we have here if I'm not mistaken) then finally Patreon at the bottom. (ever since Patreon employees finally noticed the controversial content in the game)
It is true that all the content will eventually be in the public version though.
