Hey again ! I have no problem with the implementation of the game and don't worry I understood what needed to be done. EVen more considering that all the controls are on screen.
when I said " I don't have any feedback on what I type like what I see in your video " I meant I can't see the input field which made the game quite harder with no visual feedback of what I type. And resizing the window once the game started does not work as a solution.
I just gave it another try and in the end I have to resize the window before playing.
Have nice day !
Here is a representation of my screen with the game started :
