Small note: I think I got the exact same 3 ingredients in a row for 2 different customers. It may be worthwhile adding a brief check in there to prevent that (e.g. if the randomly generated list of requirements is an exact match from the last round, just re-roll the randomiser again before showing the player).
Suggestion: Give us a ‘Copy to Clipboard’ button for our scores after each night so we can more easily share them. Or a dedicated screenshot button (we can take screenshots any time of course, but a dedicated button in-game reminds the player of the possibility and subtly encourages them to share their scores with others).
Suggestion: More randomisation with the feedback, especially when they’re happy. At the moment every single customer likes to say “OMG, amazing!” :D … Perhaps, you could even customise the feedback based on the character. Give them each their own way of talking and reacting to the same situations? (fantastic, great, good, spilled, too slow, etc)
Bug/Issue: When I close the bar for the night, a random character wanders out and says “You just spilled my drink everywhere!” (in the background, behind the scores). I assume you’re aware of this one but thought I’d flag it here for you.
