Let me start by saying this: congratulations! There's a definite leap of quality from your previous work!
The story is pretty interesting and it's clear that the it was written thoughtfully. The overall project is executed nicely, presenting a coherent visual and good experience.
That being said, there are still some places that can be improved. Firstly, the characters speech. I think it's partly because of the theme, but I do feel like they can have more organic conversation without delving too much into details and too "explanatory" (for lack of a better word). It will also be great if more of the development is narrated through the character's inner thoughts and feelings rather than outright spoken out loud. It's what makes characters more humane after all. Some parts were a bit draggy, but the interactive part elevated the issue. The rest are just a matter of more polishing.
Great work ^^
