Seems like kind of a neat idea, so I'll put some thoughts about the stuff that's there so far. Though man my ISP does some annoying throttling thing when I try to download files this big so probably not something I'll check in on again until it's much further along.
Options don't save. Also for DLSS I'd expect the usual balanced/quality/etc choices.
Text effect whilst not terrible isn't for me, I'd like to be able to disable that, and have it appear instantly for maximum ease of reading.
During the conversation then the VA just saying random stuff that doesn't match the text isn't helpful when trying to read. Also the horny sound effects need to sync up with the character's mouth during a scene otherwise it seems weird.
Portal effect seems to be a real fps killer (and didn't actually look all that neat)... something simpler might be more effective.
Body sliders don't work properly, they say they can go below the default at 0, but you can't actually make her boobs smaller. Stuff like fitness and muscle seems to be doing kinda the same thing so sorta conflict. The mouse wheel should move the list up and down when on the right over the ui, and zoom in and out when left/main area with the girl, but it does both at once so is somewhat unhelpful.
Oh also weird the outfits were each considered a "collection" and you could just toggle on and off bits, rather than mixing and matching items of clothing to each body part.
No way to exit the question list when interacting with the door, Esc did nothing but bring up the menu, can't scroll down if there's supposed to be an exit option lower... had to quit.
Scenes were basic and I presume not representative of what's intended, I won't really get into them... but as this isn't a pre-rendered thing then I'd expect a lot more interactivity and options. Need some kinda creampie physics too, possibly with some kinda dirtying system if someone wanted to try and get as much of their partner as filthy as possible with repeated uses.
