Updating the code to improve performance, customisability and avoid using dependencies

[Animenosekai]

Hello!

I just got your project on my GitHub home page and wanted to help a bit by updating the code to improve its performance (avoid recomputing things, storing variables, unnecessary loops, etc.) and avoid using dependencies such as termcolor

I also made it a bit more customizable (with global variables at the top)

I just tested it, and it seems to be working fine 👌

And I wish you a Merry Christmas!
