Just checked the developer's Patreon site. He's down to 8 Patrons with a total income of $15 per month. That's not enough to keep him in Kiddie Meals. The lure of that kind of money won't convince him to continue with this game. Would completing it bring in enough revenue to bring out another game? I doubt it. His reputation is ruined.
His only chance would be to forget about this fiasco, and come back under another name. For all we know, he's already done that.
It's a shame, but it's hardly the first very promising game that has been abandoned for one reason or another, and it certainly won't be the last.
