In the year 2242, various cosmic races coexisted in this metropolis.

As a newcomer, you are determined to open a "Galactic Department Store" that specializes in solving various cross-species life problems. During the day, you sell alien black technology to humans, and at night, you provide Earth specialties to aliens. Your small shop quickly becomes a hub for cosmic gossip and bizarre requests.

But as business booms, troubles also arise: immigration conflicts, resource competition, interstellar smuggling networks... all quietly find their way to your door. Running this small shop, you are not just maintaining business, but also the cosmic peace of the entire neighborhood.

Commodity procurement and listing: Procure goods from the interstellar market or obtain rare recipes through special events. It is necessary to balance inventory and list appropriate commodities according to the needs of different races (switching between day/night modes).

Store upgrade and renovation: Upgrade shelves, cash registers, security systems, etc., to accommodate more customers, enhance transaction efficiency, and prevent theft. The renovation style will affect the favorability of customers of specific ethnicities.

Financial management: Manage daily revenue, pay rent, goods payment, and employee salaries, and set reasonable prices to maximize profits.
