In Short: Make Tovy like Roblox Game, where you could manage things as well in Roblox's Management Game for your group. It would be connected with your Tovy website and so on.

Not sure if it's possible to do, but I feel like it would be a nice add-on so you could do things from just one roblox game.

Eventually, don't make it separate game but make like standard API commands connected with Tovy we could use to promote, demote etc. and it would log on our Tovy site as well. - This one here is a suggestion if you can't manage to do management center in separate game.
