There are a number of things that are very annoying as a user. For ex: this app is especially bad for kids because the app forces users to watch ads in order to get any rewards. In another example, it is impossible to maintain your egg 🥚 level without making $$$ purchases for extra apples 🍎. Without the egg level, you won't continue to advance levels, especially during special events. Plus the probability of significant rewards is slim to none. Also, ads don't have a mute button.
