Hey! To verify your game, you need to verify your id and face (if your comfortable), and abide to Roblox Terms of Service! After doing those steps, it will still stay as 16+ until you doing one of two things, you can make the game get a good amount of concurrent players or you can put a 100,000 robux deposit and get refunded after a month or two (this method is only for famous groups/communities that need review from roblox staff asap)!
