Hey man really enjoy your game. I can recognize the game as official and it will not be showing the warning anymore i think at least it worked for my games however you would have to publish the game on my launcher if that's fine with you. if you're interested then text me on discord atm i'm searching for games to grow my launcher which i recently made and would love to have your game there. My launcher is a non profit launcher for now so all games that are being published must be free to play.
