A very nice, interesting game. I liked the mechanics of sorting things on the table, that you can accidentally get a letter under a book with addresses, and in general it's nice to go through the letters on the table: they are piled as they are, but if you click, the letter aligns and it's easy to read where to send it. The mini-animation at the bottom as Derpy delivers the mail is pretty subtle, but it's cute too. Goofy visual style and nice music. I don't know if it's possible to lose here. The chill game I liked.
