1) Default DAZ models. No sign of the dev's interest in the game.
2) The light is disgusting. The dynamic range of the frame is missing. The light is either very bright and flat or very dark and... flat. You can't see the characters in the dark.
3) At the beginning of the game we are asked to establish the relationship between the characters. This means that no relationship is planned between them other than a sexual one. This makes it impossible to immerse from the beginning.
4) Repetitive clichés. The secondary nature of the game. White rich married American woman, yoga, pool, lesbian friend, California. It's boring and has been seen many times before. One gets the feeling that the game was made by a lonely third world teenager who only knows about Westerners from tvshow.
5) Emotional insufficiency. There is no reason to empathise with MC, so there is no interest in the story.
