Just a few personal thoughts -
It wasn't very clear when control was handed to the player (clicking on the showerhead, moving in the shop when you first enter it)
Without any kind of clock, time or anything I wasn't really sure if I needed to rush immediately to the customers or wait near them, or how long it would take for them to eat - but I did notice the first fellows food was gradually disappearing so I wasn't afraid I was stuck in an infinite or long loop at least, but I'd love just a bit more indication of time on that.
I couldn't quite tell if the Cook/Owner was purposefully speaking poorly or if it was a bit of an oversight with dialogue.
Bugs:
-Walking animation played when bending down to grab plates or place them down or put stuff in the garbage.
-When the trial day was over, I guess I clicked the door while still holding down A to walk? The result was the character bugging out and bouncing up/down like they just downed the most potent coffee in existence. Camera went a bit weird, they mentioned going to a bus stop but then the camera zoomed in on the Cook, took a bit, then screen went black and played a line of dialogue relating to the bus, I heard some kind of audio related to a bus but then it seemed to have hardlocked me there, nothing was happening.
No idea what if anything happens beyond this point in the game/story.
Honestly I liked having this game up on a side monitor and just vibing through slowly, keen to see sexual stuff go into it and overall where the gameplay loop goes, and definitely don't see it as a bad start by any means.
Edit: Hope this was constructive and helpful, definitely didn't mean to be negative in my response here.
