Edit: found the save, just had to wait after the tutorial and explore the apartment.
Just some feedback since Im stuck on Day6 (bugs i encountered that day)
--Protag sprite disappears in apartment and I can't see where I'm moving (not day 6 specific)
-Sprite of a customer gets stuck in the middle way so I didnt get to go to the cashier for them and made me lose them
-Sprite of customer doesn't show or shows late (third and fourth customer in Day 6) so if I see the last one, I already don't have time to even seat them
-Unli appetizers and at one point I can't put the dead plates on the trash.
Hopefully they get those fixed...Ill try to give the game another try again tomorrow to try get atleast an ending but day 6 is just tedious to meet quota of, I dont even know if any of the upgrades i both have an effect
