You did a great job at creating such an engaging experience from a simple mechanic! It reminded me a lot of Diner Dash, and I love this type of games. I could play this forever because of the good balance of stress from the timed factor in cooking and the customer's patience scale, contrasted with the chill, repetitive actions that have a rewarding outcome.
One issue I had was that I couldn't use all the segments of the stove cause of the page orientation. However, that added extra difficulty to my playthrough; maybe you could consider using this idea of setting difficulty modes based on the number of stoves available.
