Very interesting concept with SAUDADE. I didn't know about it!
I was impressed by the way you twisted the rules and concepts of Into the Odd. Very clever! I also appreciate the example of a possible sandbox to play in. It'll be pretty useful for the GM.
Perhaps, if I wrote one to play, I'd add 2 or 3 questions in each of the locations. You know, that kind of question that intrigues you and helps you create a situation or conflict.
