I won't rate the game/kinetic novel because it is in such an early stage and I don't want to give you a 1 Star review. But I still want to give you my feedback. I hope you don't take offense but you should have test it by someone else before releasing. I like the idea that you try something different but it has quiet a few problems. And for me there two critical ones that destroys the experience for me.
1. The common Ai problem. Some pictures have huge mistakes(Mirror in the car, Doorframes etc.). And at least one picture doesn't make sense at all (MC takes picture of Sofia in the park but it is a selfie?).
2. In this is my top problem with your game. So many times it doesn't make sense. And I am not talking about that both women do dessous pictures in the first night they met MC. I think specially in text messenger games like yours you have to really pay attention to details because you dont have pictures that help the player to understand what is going on. What do they have to imagine and so on. And if you read something like "MC: Sorry I was driving. Sonia:"Why did you reply so late?" and as a player you just go like "Huh? That doesn't make sense." And this feeling I really had lot. And the game is just like 5-10 Minutes?
Another thing would be the horniness of sofia. That's personal preference. I don't mean you have do a slow burn game but Sofia is going from 0-100 in 2 seconds
.
Best of luck with your game. Looking forward for future releases.
