Well, the Game is Saved for you when you leave a toad House or the Switch Palace and when you finish a Haunted House Level or a Fort. and don't worry about that, my english is not very good either. x'D
Ok, thank you. The game is really hard, that's why I questioned you how was the way to save, to play the game safely. Anyways, if you make a new version, you could do a manually save form, that way it could be more easy to play.
