The music is so soothing! Nicely presented. (love the backdrop) Very relaxing experience.
Personally I'd be excited to have at least a little challenge, because carrying one cake at a time and keeping only one name in mind makes a very straightforward task. My suggestion is to try and put the order board somewhere out of the way. In this way, the player could save time if they remember more than one order at a time, but if they forgot they would have to sacrifice precious time to double check, this would introduce a risk and reward factor which could increase engagement.
