Hangman-game web app using next.js 14, redux-toolkit and Sass

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

This was my first project with next.js, I tried to follow the same practices that the documentation of this framework uses but I don't know if I did it correctly or if it is the best option, I would be grateful if you could tell me if I did it right

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

I had problems when I wanted to transfer data from one page to another without the user being able to see what data it was, the solution that occurred to me was to use redux-toolkit but I would be grateful if you would let me know if there is another simpler alternative.
