It depends on what a person considers a scam, the game was updated recently but little was changed. It may take literally years for this project to shape into a real game. And Helius has a tendency to abandon projects or go back on his word/change his mind mid-development.
Maybe he will finish this game one day? Yeah, maybe.
Maybe he will abandon this project mid-development and port the assets to a new project? Yeah, maybe.
