Grocery Store Tycoon - First Store allows players to take their first steps as a store owner by managing and expanding their very first shop. Start with a small store, optimize its layout, stock shelves efficiently, and serve customers to grow your business.
Hmm, it doesn’t call itself a demo or otherwise imply it’s not a full game anywhere I can see
It looks like the page for what will presumably be the paid-for game is here:
https://store.steampowered.com/app/2870330/Grocery_Store_Tycoon/
Not released yet, though.
Being it calls itself First Store, I’ll infer that this is a demo. Not unlike all the other demos I run across saying first chapter.
There is a website I get in my Google feeds that always advertised steam free games and they turn out to be mostly demos.
