About the game
You work at a small post office on an island run by cats. A boat brings parcels, and you weigh them, stick on the right labels and find a place for each on the shelves. Customers ask for a parcel, often with only a vague hint, so you search your storeroom for the right one. Then you pack outgoing parcels onto the boat.
Up to four people run the post office together online. The jobs split up on their own. You can serve customers at the counter while a friend sorts the boat's parcels and another loads the outgoing shipment. Shelf labels keep everyone on the same page about where things go. There is no timer, so nobody has to rush.
It suits friends who like tidy shelves and easy talk. A messy storeroom can slow the whole group down. The story takes about eight to ten hours, then an endless mode lets you keep going.
