I understand needing to rework the game, given the difficulty working with the older models and all but the introduction to this long wait is pretty weak. The heaven and hell bit is pretty long and drawn out and the characters that most of the sex scenes are with bald and faceless models. It'd have been a better idea to spend the effort to progressing this plotline to more desirable characters and making scenes with them instead. I couldn't care less about fucking a bunch of faceless demons in a dungeon or the light soul at the start or the demon guard. The only one that makes sense plotwise is the light angel at the start because she turns dark when you cum inside her and that's a plot point in of itself, but every other faceless demon we fucked along the way served no purpose really. Definitely could have scrapped those bits for something else.
I know it'll get better once we leave the heaven/hell section given the quality of the other version, but this is a WEAK opener to a remake.
