Loved the feeling of this one! The low-poly graphics were vv cozy.
As I was playing I felt as if a little direction as to what each customer might like could help. However you'd like to balance the game. I never really knew how exactly they felt or what they liked or didn't like based on what I was doing. There's a lot of creative ways to display some kind of hint to the player that'll still make it feel like a puzzle.
