As far as the prologue goes, this is a solid start. The story is decently well written and characters are interesting and consistent. There are no choices to make but it's a kinetic novel so we knew that from the start. But I do think that the MC's blackmail is a bit weak to do all he plans to do by the end, and that Sal is the best character.
Render quality and models are pretty good, and they look original to this game which is a plus. So far there are no animations, so can't judge on that. There's music but I turned it off and heard no other sounds. And I found very minor loading bugs, but those are probably due to the computer and not the game.
So, all in all, a very good start. We'll see how it evolves but it could very well go up a fifth star if done well, or lose and go to a third one if it doesn't.
