Hey man, please don't worry, it didn't come across as rude at all. I completely understand your point, and I really appreciate you taking the time to help improve the visual novel.
Regarding the name, it will make a lot more sense in the next update. Very soon in the upcoming content, when talking to one of the girls, you will recall your name, and from that point on, your chosen name will be fully integrated into the story. You are only "Zero" at the very beginning because the corporations treated you as a mere asset, but upon waking up, you will show that you are still human.
As for the dialogue box, I can definitely look into improving it and adding a transparent option. This is actually a perfect opportunity for a poll! I can design a few different UI styles, show them to the community, and let the best one win. I'll make sure to set that up for the next update.
About the NSFW scenes and dynamics like femdom, whether a specific scene happens or not will depend entirely on the choices you make. Everything comes down to your personal playstyle and how you want to shape the encounters.
Thank you again for the honest feedback. I really hope you stick around and continue following the game—please don't drop it just yet!
