I think the big thing with this game is know what you are paying for/downloading. I'd say to people trying to decide if they want to give it a go -
If you are looking for happy endings - this is not the game for you.
If you are looking for a romance game - this is not the game for you.
There is still a lot the game can offer - but if you have expectations of something else, then you WILL be disappointed. Personally, I thought the game was something it was not. That is probably my fault for seeing the words "love interests" and thinking "twisted romance" still meant romance, and expecting there to be a happy-ish ending even if it was "bittersweet".
I'd have also suggested a massive warning around consent which is absent from the warnings section, but that's me.
