Hey! I am focusing for the moment on Gwendolyn, I am also preparing an event concerning her, but I will add other girls on whom we can use some powers, however Gwendolyn will remain the main girl, the others will be secondary and will have less interactions (like saleswomen for example)
Just wanted to chime in here and thank you for keeping the main focus on a single character. I really think trainer games like this are far better when there are fewer characters with more interactions rather than more characters with fewer (or copy/paste) interactions.
Keep up the great work! I played through most of the content after your previous update so I'll be holding off on playing again for a while, but I really enjoyed what you have so far and there is already a solid amount of content here for as early as it is in the game's development progress.
I also really like the whole idea of filming your interactions with her and playing them back. I'd love to see this concept explored further, especially taking into consideration her altered or different mental states (mind control / horniness / anger / shame / etc). For example, it might be interesting to see her reacting differently to seeing a recording of you having sleep sex with her, depending on her current mood/mentality. There is already an element of this present but I think it might be fun to see it expanded upon.
This nuance will probably require far more development time than it's worth, though... definitely focus on whatever you think is most important to the game/story first! What you have here so far is awesome.
