8/10
I love games where the difficulty curve contributes to the story; this game really nails the fun of getting good at a job, even if the job isn't something people would immediately consider "fun."
getting to the point where you don't have to check the addresses during delivery is super satisfying. same goes for getting into a flowstate with the sorting game. it would've been cool if the special delivery event had some unique gameplay, but thats the only aspect that feels underdeveloped.
