Hi, I was just wondering if its possible to delete a game you just created, I think I messed it up somehow and want to start over :/ If I can delete it and create a new one under the same name is that okay?

Go to the GM Menu (link near the right hand side of the header bar when you're in the game).  The bottom section of the list of items, "Game Maintenance", has a link to delete the game.

And yes, once the game is deleted you can create a new one, or resurrect the old one.
