Thanks for the detailed feedback, that's always welcome.
As for the grinding: there are good ways to make money, first the blond host guy and once you have x-ray/hypnosis the income is quite high. I'll keep on adding more sources for earning money in the earlier game, but overall I see player not having much issue in the longrun.
The photo system is already setup that it does not repeat a photo before you have seen one. e.g. when you do panty shots or x-ray photos you will always see new photos until you have seen them all.
For hypnosis it is the same, but they are categorized to body types and the different poses. The Photo collection shows you the body types and poses you are missing. Note that you can see the the body type of the woman in the text before you go to the alley. At that moment you can abort the process when you don't look for that type.
Exploration and trial is wanted, RNG not really. The game has a number of upgrades to make progression easier, like easier minigames, more film capacity, etc. I have plans for elements like walk-speed upgrades, and I like the idea about skipping the bra part. I will add it to my list. In polls, players currently request more story content, so I'll always balance the efforts on that.
As for some photos being "borderline disgusting", this is something I've never gotten as feedback so far. It's true that I use a dedicated ai model to generate the basis for most photos (~280 now), but they are all overpainted. If there is a picture that appears off, I can always fix it.
