Oh, my God, I'm thrilled with this game, the music, sounds, visual effects - all this pleases my eyes and ears (and I've played many novels, believe me), so, as for me, this is a very good start for someone who has never done this, but for the demo- it's even very good.
Well, then I would like to express my opinion about the plot... The plot is not bad, it inspires good hopes, but I think that this demo version is like a continuation of the game that has already been completed, as if we should already know what he was like before the main character ran away from him, and understand how broken he was that he decided to do this, it's the experiences of the main character himself, but that's just my opinion, but I understand how difficult it is to write the story and character of the characters in principle, and it's not easy, so I think it's just a matter of hard work
