When you get full, you instantly get a message, "You are now full and shouldn't eat any more." This is good. However, the icon next to your character on the game screen, and the icon on the left side of the screen below the map, it does not immediately change from the hamburger icon (indicating that you are eating food) to the green frowny face icon (indicating you are full). The correct behavior should be to have the icon immediately change from the hamburger icon to green frowny face icon the instant you become full and simultaneous with the "You are now full and shouldn't eat any more." message, rather than after a delay. The delay in practice can range from a fraction of a second that is barely noticeable to several seconds. The delay is especially longer if the food you are eating is one with a high frequency number such as 25 or 20. Foods with a low frequency like 10 or lower have much shorter delay before the hamburger icon changes to a green frowny face icon. Anyway this delay ought to be eliminated so that users know immediately that they are full, not just from the message that appears at the bottom of the screen, but also from the icon changing simultaneously.
