Very good
The story was a bit complex twords the end but I think i understand what is going on based on your description. The art was pretty well done and the animation was smooth. I think at one part there was narration of the text on the screen but I could barely here it (compared to the volume of the rest of the movie). Besides that it was a pretty cool movie with a sinister ending.
I'd say this is the best of the NG movie jam since it had a good story and no uneccary beastiality. Good Work!
