Overwhelming ads disrupt gameplay experience and are difficult to close. 2. Inconsistent rewards and lack of clear progression system frustrates players. 3. Limited customization options for characters and school settings hinder creativity. **Pros:** 1. Addictive idle gameplay mechanics keep players engaged for extended periods. 2. Customizable characters and schools offer variety and replayability value. 3. Relaxing atmosphere and calming background music provide a soothing experience.
