Deep storage

You mind a warehouse on the rings of a black hole.

Clients dock, hand you something and ask for it back in a hundred years — the world's years, not the thing's. Deep rings run slow: what waits down there barely ages while the world outside races on. Stand deep yourself and the world races too. A step in the outer band spends a day. A step on the deepest ring spends ten thousand.

Nothing outlives a year of its own time. Clients do not wait past their window.

Every press burns fuel, and only a delivery brings more.

Time moves when you do. Nothing ticks while you look at the board.

HOW TO PLAY

Arrows / WASD   move one cell — climbing to a shallower ring costs two steps   
Space           take an offer, put a thing down, pick it up, hand it over   
Z               wait one step   
Esc             close the offer menu   
R               new run   
T               the same seed again   
M               sound off

A delivery pays fuel worth the years the client waited. A thing that rots, orarrives after the window has closed, costs 400. When the fuel runs out you arefired, and the plate tells you how many years you kept in storage.
