I actually like this game a lot. I have to admit I'm rushing through all the submissions this time 'round so I didn't go all out for any game but a collection of random things I like to follow:
1. The water meter is not too obvious. I don't know if you meant for it to be so but it makes me feel like it's easy to forget my own safety and comfort among all the other tasks I must perform, which I think is really fitting.
2. I like how customers can be a bit annoying and ask for the same thing twice in different quantities. This makes me think it'll be fun if you serve a customer, who then quits the line only to run back, cut in and demand more stuff
3. I like that each "screen" makes it impossible to see the others so I always feel like a low-paid worker toiling in a fast food job, having to focus on my current task but also knowing that other shit are happening in the background
A small immediate improvement I can suggest is just to make the UI a bit more obvious at some points. It's by no means obtuse or complicated, but just a bit hard to read on some overlay.
Thanks for making the game!
