Well, few week left. I was trying to contact artists. Got answer only from one, saying that I am free to publish game on itch.io, but no single word about github. I asked again, and no answer. Looking on your replies here, I see that licensing and copyrighting is very difficult and dangerous. Thank all of you, it was very useful.
I published game on itch.io. https://heathro.itch.io/lost
Later on github I will leave code to public access, as I said before that I want to use in searching a job, to add this to my portfolio, But I will not include any assets there. only code. If some technical specialist interviewing me, he can look on the code, he do not need pictures and sounds. I think that will be most correct way to do this.
