Very, very ambitious! I hope you continue to work on this and it gets somewhere. If you get a patreon, and if it looks like the updates are continuing, I'd be more than happy to back this project. I downloaded and just got done playing for a few hours. Here's a few things I noticed, and you probably know a lot of it already.
While the game definitely has got a lot going for it, but needs quite a bit of polishing yet! The text during sex scenes is way too fast! I'm a native english speaker and trying to move around the camera while reading is next to impossible as it progresses on its own too quickly. You did a great job on the writing and descriptive narrations, so give us time to read it!
The animations often don't line up (cock next to head or through the back of head during a blowjob, for instance) I used the page up/page down cock feature and that seemed to help some of the clipping, but sometimes the cock just jabs out of the back of my skull regardless.
The city being completely untextured makes moving around quite difficult, and I'm not exactly sure how everything works. Even just having single colored textures on the different kinds of buildings would be a huge upgrade. (red for commercial, green for home, etc) Some sort of tutorial (in game or a text file) would be very helpful to learn the ins and outs of what you should be doing and what the backstory is. I see the tutorial video above and will check it out, but not everyone wants to watch a video when they could immerse themselves in a world like this!
There's a lot of clipping with outfits as it stands, and the model continuously smiling during character creation makes it hard to adjust facial features as the resting face differs quite a bit from the smiling one. Also need some open mouth facial expressions for blowjobs and fucking.
Many of the issues I'm seeing right now are cosmetic. I really hope to see you do more with this...don't give up, it could be something really, really epic in adult gaming.
