The new house design looks great, it will make the stories work so much better as I already expressed concern with previously.
I'm very happy that you are able to use your own models also. Variety is the spice of life. It looks like you're heading in the right direction already, but making the girls be very different from one another is very important IMO. Even intentionally making some less attractive is interesting to me. A redesign of all the current girls would cover most niche's that people have for typically hot girls, adding a few more slightly more average girls with less involvement in their stories would really fill out the game and put the party in house party. Even if they are just sub characters that you can't seduce, or can have an input to another characters story (threesome, lesbian, getting with another male npc etc.) that would really flesh out the game and add variety. Don't spend too much time on them or anything, tweaking existing characters into less hot versions with a different hair colour would do personally.
As for the direction in general. I think the quirky puzzle take is refreshing in the genre. My only wish is that it gets more challenging, or at least have an easy standard ending with a character and a harder to obtain ending that involves timing things with other characters better or making choices between who you want to focus on (like ashley vs madison). This allows for a quirky fun game for the standard endings but gives a challenge and is slightly more realistic for the harder endings.
Best of luck and I hope the new flexibility allows for the sex scenes to end up better than they would have using daz models.
