Tic Tac Toe with NextJS

What are you most proud of, and what would you do differently next time?

I wanted to test my skills with NextJS with a more complex client-side project, so I thought this might be the perfect occasion.

Although NextJS is not the best framework to develop a project with this characteristics, I managed to complete it as I wanted to initially.

What challenges did you encounter, and how did you overcome them?

The most difficult part was thinking of the best folder structure and file management in general, also managing the game state and thinking about how to program the user movements and CPU's too.

What specific areas of your project would you like help with?

I think there is a lot of code to be refactored yet, so I would like to receive some feedback about the best practices to refactor my current code.
