This game was really excellent! One that I will be replaying long after the rating period ends. I can really tell that you took the jam seriously. I like the well thought out, high quality sound design and chill music. I like the funny voice script, the excellent [and well recorded] human voice acting, and the humor injected into the AI voices. I love the player comfort touches you added, like F as an alternate cup throwing key, Q to skip the tutorial and R to repeat a line, and that you took the time to make such a comprehensive help menu. This earns you a few cognitive accessibility points as well!
I do feel that some quiet background ambience would liven things up a bit, and some kind of reward for being fast would be cool too. As it stands, the game is quite forgiving, which is nice, but a harder mode with penalties for failure would be an exciting option to have. Saved progress would also be a nice to have, but it's not that important in a jam game. As well, more randomized customers would be interesting, though I understand why they show up as a progression ATM.
Thank you very much to everyone who worked on this game, you seriously kicked ass! And just sayin, if you decide to add to it a little and make it a paid game, I would absolutely buy it. Hell, I'd buy it in it's current state as well, if that was an option...
