All games of this author do not have a save system, I'm not a paronoik, but it seems to me that some kind of mining is built into them, people have to play with each version for several hours to get to new scenes, while the load on the card is 100% with not very good graphics (3080ti)
This might makes some sense, but my VGA it didn't heat up as much as some other Unreal Engine games out there (this game is optimized), I'll still look for information to know more about it, games with programming to mining. I find this game difficult to have, but as you said that all games by this developer don't have a save system, it's weird. But as someone else said, the developer edits some existing parts of the game, for example, as it was in the case of Tuesday that he put bestiality content (minotaur VR). I gave up on this game, it's not a 3D game that you have freedom, eg Last Hope, even more without a save option, it's disheartening.
