It was decent, the only thing, unless I'm missing something.. there's no "quit" option that I could see so I alt-f4'd out on windows.. and I would kind of like to turn the music off, I couldn't find a way to do it.. only reason I even wanted that was because I was watching something while toying with it, sometimes it would be nice to mute in-game music without having to go out of the game and muting everything :)
I'm a fan of Jack, but I didn't find you from that.. I just started scouring itch.io myself after updating my gaming system.. happened upon this .. thumbs up!
You can quit by hitting the pause button on the bottom left side of the screen while on your next customer. You can turn down the music and stuff in options or hit main menu to got to the menu. You can quit from there.
