You know when you look out the window and you have a random thought about a thing you notice happening outside, and instead of moving on with your day you just continue thinking about it, making up scenarios and answering hypothetical questions...
This is what this game is: a sort of wild tangent about postal workers and what they do while delivery mail (especially what they talk about and who they talk to). It is somewhat absurd, quite comical, and lovely in its mundanity.
The formatting and UI of the piece (shaped like an envelop, filled with all the required stamps, and sometimes extra stickers) propose a fun way to interact with the piece (and mimic how non-sensical/linear those wild thoughts can become). I really enjoyed clicking on the different postal-related images, to move the story forward or cycle through options.
A very fun way of using the medium!
