It has been answered I think a lot in this thread, but the game only allowed you to save at little sign's if I remember right, you'll find them at set locations through out the world inside and out.
I think it was a dumb Idea, that just complicated the game even more than it already was.
I assume the maker, Maker's were trying to stop save spamming, which some people proclaim are ultimate cheat's. ( I am not one of those)
the artist is making another game and its release date is this year. im hoping more futanari like in this game. the xu
and sher side story is so hot in this game.
For your sake do not play this game, I came in for the art and sexy and stayed for the good story but one ending already broke me (b), it left me a wreck, i don't know how (a) ends yet but yeah.
