Many words, no clear answers.
2 things mostly answering on my question in "help" section:
1) if you download version from itch.io (0.6.5F) -> its old and with bugs, and noone cares, because its not paid
2) there only one path for every girl so need to replay all game from the save point, for every one of them, sad if that so...
But anyway, if its not a bot - thanx for reply.
