Possible disadvantages of Flexbox Defense

    While the game introduces basic and intermediate Flexbox concepts, it may not delve deeply into advanced Flexbox techniques or real-world application scenarios.
  • Not Comprehensive
    The game is just one part of learning CSS, and users will need to supplement it with additional resources and tutorials to gain a full understanding of web design and development.
  • Requires Prior Knowledge
    Beginners who are not familiar with basic CSS and web development concepts might find the challenges difficult without some prior knowledge or learning materials.
