Very cool Markus! I had fun with this. Looks like you nailed that graphical style you were wanting. Obviously gives me 3DS Animal Crossing vibes serving coffee at The Roost. :)
A few things:
1) The day never progresses past 'Monday' on the results screen. Maybe it's just always Monday in Purgatory, haha.
2) I would accidentally read the ingredients list instead of serving to the customer, over and over. Perhaps removing the ability to read the menu when you have a coffee in your hand would alleviate that.
3) Did washing dishes accomplish anything, or did it count as a cleaned table as long as they were in the sink? If so, some sort of drying rack that fills with washed cups would have been some good visual feedback.
4) This game didn't play nicely with my ultrawide monitor. A windowed mode in the options would've helped with my very first world problem.
But yeah, overall very cool. The music really fit the vibe well too, nice work Samantha!
