Good day to everybody! Really appreciate all the comments, thank you for sharing your opinion.
About the name and the actual game "The last of us": I've never played it and I don't want to make a parody of the game or something like that, I just found the main characters' type very appealing for me to create a game with the same kind of characters, the type becomes quite popular now (for example the movie Logan, also a man and a girl). And I also really like the name Ellie, so I didn't even try to make her look like the actual Ellie, just the "type".
About all the incest thing: I also agree that mom - son is more overdone now than father - daughter. But in future plans I was thinking about creating four character and give the player a possibility to chose 2 of them in the beginning and the possibility to play each of them. So it could be husband - wife (for those who doesn't like incest and would prefer just a romantic story about taking care of your loved one), then father - daughter, mom - son and brother - sister. But for the early time of the game I think I should make at least father daughter good and then proceed with the other types.
About daughter's name: in one of the future updates I'm going to add a possibility to rename her as it is very easy to do and se is already coded as [dname] in the whole game.
About the "i wanna eat your pussy" and "if you say so thing": she answers with those words only if the reply for your words/question is not coded yet . And I decided to make it like a sarcastic "If you say so". And she responded for "i wanna eat your pussy" like that because of the word "wanna" she doesn't know it yet
For now I've tried to predict the players input and it contain a small base of standard input phrases so in future, she'll "know" more phrases to reply for.
About question "daughter is just "a thing" not a goal": I would be very happy to do the game about corruption as an innocent daughter would be a more interesting character, than a "slut daughter". But sadly, scenario and dialogs is the hardest thing for me to do now and I think, I'll just find a person to help me with that to make the story more alive and interesting. And it would let me focus on improving my art and coding as I've done it only for couple of months and have a lot to learn on that part.
And the last one about the customization: I think it would be a good idea to add a possibility to add some options for the daughter's look like hair and eyes color, breast size and other stuff. And the main character doesn't appear anywhere except his lower part of the body, so the player could easier relate himself with the protagonist.
Thank you, everybody again, hope you'll enjoy playing the game!
