Okay, so as much as i don't want to review a game by suggesting to completely reverse the basic idea of it, i must do it here, and it's just my opinion, so game dev can take it or leave with, but it's with best intentions.
I think this game would be much better if it's reworked to just play as female protagonist - mom, and find a way to present what happens to the son in some other way. Maybe keep the story POV limited to mom, but do some omniscient POV just for the son, or maybe son tell mom what happens to him at school, and we see those scenes in quick flashbacks, and that way you keep limited POV but with exception. That way the game still has those NTR elements that some enjoy, but it removes completely pointless element of playing with the son and makes the game much better.
The story is presented very weird because the game is already 50/50 in terms of POV - it's kinda limited in some aspects, but it's mostly omniscient POV. Dev needs to decide and keeps the story more organic by deciding what he want to do there.
I like horror elements of it, the proportions are great, the interracial stuff is great, the models are great (even tho we all know they are created and used in many other games), and the story is not bad, it's just presented in a weird way. Animations need to be improved tho.
