I am really impressed with your work. I love how natural all the characters feel with their own personality and not like another standard porn character. The dynamic between the girls alone is something you rarely see done so well.
I can count on one hand the games with a male character as good as Ian. If you told me that the next episode would only be between MC, Helena and Ian, I would be very happy.
You have so many turns you can take with the story, which is really refreshing. You said yourself, why should the girls work so that MC can leave with them. You can even have one girl turn on the others as a twist.
On to the things I don't like:
Why should MC believe in the Pusher? He is not there when the effect happens, there could be no effect at all and MC would not know it. There should be a scene where MC sees the effect or benefits from it. Zoe could just get lucky with her tips...
Why does MC tell Bianca about the Pusher? There is no reason to tell her.
Finally, I understand about the raw packs, but it hurts the game. You have this scene that some might find erotic (I don't like bondage, tentacles or NTR, and I'm still here...) and then this kind of popup, it just feels cheap. Put it at the beginning or the end, but not after a scene.
I hope there are some scenes for people like me who like to corrupt their girls and have fun with them without bondage, tentacles or other guys. Anyway, keep up the good work! Again I am really impressed.
