Possible disadvantages

    While ct.js is great for beginners and small to medium-sized games, it may lack some advanced features and tools found in more established engines like Unity or Unreal. This can be limiting for more complex projects.

    As a JavaScript-based engine, ct.js can experience performance issues, particularly with larger and more resource-intensive projects. It may not be as optimized for performance as some other engines.

    Although the basics are easy to grasp, some more complex features may still have a steeper learning curve and require a deeper understanding of JavaScript and game development principles.
