The idea for this game is good, but the execution is wrong.
- The pace is too fast.
- You have to flesh out the relationship with the wife. The player must feel an emotional connection to her before the NTR and cuckolding.
- Talk to her about non-sexual things a little over dinner or something.
- Talk to her about sexual things:
- She's going to the gym, she asks which workout outfit to wear, the sexy one or non-sexy one?
- If you say the sexy one she'll say, "but all the guys will check me out at the gym, are you sure?"
- She's going to work, she asks which outfit she should wear, sexy or non-sexy
- if you encourage her to wear the sexy outfit, she'll say "but honey, all the men at the office will look at me with naughty eyes"
- Once you've developed an emotional connection to her, THEN you bring on the slow build up to NTR
Okay, what's your favorite erotic story? Think about that story. Now cut out the first 30% of the story, would the story still be erotic? No, because you cut out the build up. Every story must have a build up to a climax.
In the case of your game there isn't a build up, it jumps straight into the climax.
It works as a prototype. In it's current state, it's a bare bones structure that can be filled with content, so at least there's that.
Just want to help, take care!
