Thank you for this link.

That means whatever category the license might be, l am free to copy it and create my own work, right ?

That link is extremely valuable. Thanks.

That’s the fundamental purpose of my developing the game.

I mean, the game should be based upon git entirely.

Is that some game on GitHub ?

I don’t get your closing sentence.

A video game ? Based on tui ??

Wow, lovely ! Maybe l could make changes to this, and come up with some new games ?
