Tic tac toe game (added play online feature)

Hello Wazza, amazing project you got here, congrats on finishing it and holy the online feature is awesome! great job

I'm myself doing this challenge and is quite hard (at least the CPU gameplay), I will for sure checkout all of your code to see if I get some inspiration!

Thinks that I notice while playing the App that you can change or improve:

• The CPU plays too fast (also seems impossible to win but this is ok, hard mode always), maybe add some random timeout between moves with a paragrah rendering with 'cpu is thinking...' or something like that would be awesome.

• Some transitions between screens would also be awesome, I am trying both of this ideas in my own project, inspirated by: benja.min tic tac toe solution.

• As a last advice, this is a challenge that has some hard work done but you forgot some of the more 'tipical parts', the title and the favicon is still the default from Create-react-app.

Apart from this trivials suggestions, you inspirated me to don't give up on the tic tac toe challenge, it is a shame that I can mark as helpful your project! haha

Hope my feedback helps you!

Edit:

• Would also be nice if you create a .exampleenv to see the environment variables you did use on your project (with dummy values of course)
