17MOONKEYS You wanted some honest feedbacks so...
1. Great Renders
2. Good Models
3. If option to exclude Futas best is conversion. I know more work but still would apeal to those who are turned off by Futas.
4. Hair optional or removal. Shaving may be included.
5. Upgrade option on protagonist like growth and may be give some muscles to him. he looks like a sissy boy. Cmon... As far as I understand it's a Harem Game with only 1 male character. But does he have to be so tiny, lean albeit a Huge dick. Give him some height. He looks to be no more than 14-15 years old. Maybe a nerd but he definitely needs some stamina to keep up with all them Bazoongas.

However, This is just honest suggestion. You might include some training regimen or a serum to make him look more mature and stronger to handle stuff.
6. Love the Dick monsters. why not make them attach to MC to get extra dick????

) (not sarcastic) might be cool.
7. Love the concept of AI Sexdolls.
8. more expansion of the space ship with additional "entertainment" rooms.
9. why only Big boobs and big asses. Include some petite or moderate forms too.
10. there's a big area of expansion with sex toys and accessories you might want to look into.
Overall, I'd say good job but you really need some concepts for sustainability and avoid boredom. Hope this helps.
