If this goes to Steam in its current form, it will get review bombed into oblivion. Dude doesn't listen to the following he has; the Steam Community will eat him alive. Idk, maybe that will wake him up, or more likely he will abandon it. Either way I don't see it being good for him. He can't get Patreon support because he ignores his Patreon's feedback. Sticking to your vision is one thing, refusing to fix your broken, pointless game is another.
This game is utterly broken with a lot of the UI just going to waste, I had played this game first around a year or two ago, and left it up until recently, There's been a few updates, but nothing to the story, no extra scenes and still plenty of bugs, if he's working on a new version for Steam that'll be a major update in terms of content and or bug fixes or whatever, then awesome, but in its current state, this game will not survive at all.
Cubeworld comes to mind also, when that released on Steam, it was an older version with a different gear system, and everyone hated it, and it's been a long while since it was last updated, a good few years of complete silence.
