I made it on purpose that if the couple is too eager from the beginning for the cuckolding, there will be some loss of control in the relationship. That is closer to truth than fiction. Also, there should be up and downs in the relationship to overcome even if they have a respectful relationship. Or the story can become boring. It's not a vanilla game.
I see that the game has caused you enough angst to make you feel very upset, yet attached enough to complain and give a low rating. I'm not complaining about the rating or the comments. I can see from your comments how much you have loved playing it. I actually love to see such a strong reaction from a player. Because it is a success for me as the developer. I made a player feel at least a hint of the angst and thrill a cuckold experiences in real. Sometimes, I can be a mean one at times as a writer.
Because, in reality, I doubt a relationship can be all flowery and perfect if a couple goes into cuckolding. You can't go offroading and expect a smooth ride.
Please use the short guide in the game and try some other recommended routes. I would love to hear your reaction to them.
