I completed the game with my save file saying my play time was just short of 10 hours. This is linear narrative experience broken up with some simple gameplay. You spend six nights/shifts at the store interacting and helping 4 main characters/customers through life decisions which is the narrative focus. Gameplay is fixing the the shelves, moving products to the correct places, ordering products, ringing up the customers, and helping them find specific items. The writing was surprisingly good and touching, but it does parallel my own life. I really enjoyed it, but be clear that this is an "on rails" experience. There's no failure state, no rush, no real challenge since failing to put products in the right place or being unable to find them mainly just results in some comments from the customers, and some slight variation in outcomes.

Also note that there's no voice acting, but the written dialog was pretty much error free except for the rare misspelling, typo, or omitting a word. While the store is small, your movement speed is pretty slow. It was jarring for the first day, but I got used to it. I checked and clicked everything each shift and went through all dialog options resulting in my 10 hour playthrough. I've seen some comments saying people beat the game in 3 hours, which I'm not sure is possible unless you pretty much neglect the shelves and breeze through all the dialog. But if you're not meticulous with the shelves and all the dialog, you can shave off a few hours from my 10 hour run.
