This game has been out for too long to change any rules of any category at all...

Once you start a new file, the game saves automatically after the intro cutscene, so if you feel like you messed up anywhere, the file is already created for you to start over.

As I'm hoping you are aware, RTA for Individual World runs, timing starts on the input when you move across the map, and not on the file select screen... In fact it's like that with every category.

Also, if you are doing a world that isn't W1, just save after when you enter the next world. That way it's easier to set up.

Hope this helps <3

Fixed it! Hopefully it makes more sense now!
