As a player who has played this game three times, I have to admit that this game is very attractive. And I also have a few comments and suggestions about your game.
Strong points
The plot of the game is very well built, players can see the whole process corrupting of Erica
Your renders are really beautiful, arguably the nicest of any game I've ever played
The animation is quite smooth
Weak points
The plot is meticulously built but somewhat simple, if you only focus on the NTR story among Erica, Sato and MC, the game may end soon
Renders do not depict the whole story that happens in the game, or in other words, quite few renders. That makes the gamer’s experience quite limited
Finally, some of my suggestions, hopefully can help the game become better in the future
Building the story of the wife's infidelity in detail is a very successful thing of the game. However, in the future, if it remains the same, it may be difficult to exploit further. So I think we can split the routes for Erica later. First, I call it prostitution, then in this route, Erica becomes decadent and be slave of sex. The kind of person willing to make love anywhere. Then she ‘ll try horrible things like piercing, anal, double penetration, tattoos,... Thereby, emphasizing her corruption. The second route, I call it fendom, in this route, Erica will not corrupt but become strong, decisive and talented, although addicted to sex but will not arbitrarily have sex with anyone, like a rich and powered lady.
My second idea follows on from the first one and comes from the game name chronicles (I don't know if my idea is the same as yours when naming the game). The story happens after the player has completed one of the two routes. Then we will come to the latter, temporarily called the present, in the present Erica has an affair and becomes a fendom or prostitution, and the story played in the previous part is the past is told. The purpose of this next game is the process of reclaiming the wife. And in this story I think you can let the MC bring elements like BDSM, mind break or even use drugs to reclaim Erica.
Those are all my comments and suggestions. Hope you develop this game far beyond v1.0 because after all, this is a potential and popular project.<3
