Echoing what others have already said, I would definitely like to see a lot more content...And at the end of that content, all of the characters should have an "under development" or "end of content" message. I know some do already (e.g. Hikari nude pool scene), but some scenes seem to be infinitely repeatable with no notion of if it's progressing the story or not (e.g. Maria Massage & Daisy blowjob), while others seem to just end with no mention of when I should expect it to continue in the current build or not (e.g. Amy after the shopping event).
Another quality of life adjustment would be a tracker of where women are currently located at any given time - with maybe a portrait icon or something - as there's a lot of needless location swapping atm.
Considering the fact that you are a personal trainer it would be cool to potentially influence characters' outward appearance through the use of specific training or something but im afraid that'd add way too much of a workload!
With all that put aside, I'm really hopeful for the game, the women so far seem great and I can't wait for future updates!
