I would like to congratulate the game creator on the huge improvement in the game when switching to Ren'py.
It's very good indeed.
I agree, it's a huge improvement, but the story still needs major work.
For example, during the gym scene, there's no element of build up and then climax. It immediately reveals that she's sleeping with her trainer. Instead it should only hint at it, then it serves as a build up for the climax of seeing her fuck the trainer in the bedroom at home. Now, that can be one angle. Another angle is where you discover her adultery before hand through conversation perhaps, then you accept it, then you see the gym scene where she openly is close with the trainer.
Another problem is the wifes eyes, something is wrong with the eye shader and material. I strongly suggest the dev get a new eye material from daz studio for the wife. It would be easy to do spot renders over existing renders which shouldn't take longer than 2-3 minutes per render, then in photoshop you can over lay the new eyes. He could also just use the eye textures from the new characters he made, their eye materials look totally fine and proper.
If he heeds this feedback, the game will keep improving exponentially.
I can totally tell the dev listened to all the previous feedback and included it in this new update. I commend him! He's doing awesome work so far! The game has amazing potential to be a super hot NTR game.
One more feedback, the animation in the beginning doesn't look right, especially with her eyes. It looks like she's a robot doing a dance, more like malfunctioning. Get a new eye shader asap! It's a huge problem.
She's also way too muscular IMO, maybe tone it down by 30% then add 10% more voluptuous. If you want to keep her super muscular like that, it's probably wise to explain why she's into FBB style workouts with 4-5 sentences somewhere. It's important to explain because most house wives are not into FBB, it's out of the norm. Anything way out of the norm should be explained to enhance believability.
