I just finished playing the game in its current state and I absolutely love it. It's got a few rough edges but the premise and the long-term focus on your content creation has me really looking forward to following its development!
A bug I found: I too had a period where the massage parlor was unavailable and I wasn't clear on exactly why. I had visited it daily testing the different sessions in escalating price to see what effect they had on the player and it was after the blowjob that they became unavailable for a period of time. At least a whole week, maybe longer (I kind of lost track of in-game time).
I also missed that there was no further content after 30th of July but the game went on anyways. I didn't get a text about no more content nor anything like that, but I did notice that when the first of August came and employee salary was going to be charged, the money didn't disappear from my bank account.
I absolutely loved the medical examinations and how accurate they were in terms of terminology and in giving feedback on what your choices and questions were to the patients. A fresh angle to what otherwise could just have been another visual novel/dating sim.
In regards to feedback for further improving the game, apart from adding more content (which you're obviously already working and planning for), I'd try and add a little more variation or random events in the other spots around town. I haven't checked your patreon site yet (but I'm definitely going to after I write this) so I don't know if you're already planning for it, but having something happen in the bar, gym or pool would definitely make them more interesting than having them affect a stat that is already very easy to max out. On that subject - charm is very easy to max out, sexual experience/skill is invisible to players, which might be a little frustrating (albeit realistic) never being completely sure of quite good you actually are in bed.
Also, it'd be really nice being able to go to the park on an afternoon off-duty (and maybe having some ice-cream? *hint hint*).
On another note, I tried a few things but never could end the examination with the young girl and her older abusive brother without him leaving and taking her with him in a fuzz. It kind of broke my heart having them leave like that and not being able to help her in any substantial way.
I really hope you're planning of adding some sort of follow-up to that in future story.
Also, the priest giving the main character a job offer of that type so quickly without knowing him or anything was very abrupt. Maybe writing in something that escalates to that level might be appropriate to make the transition a little more natural. Like, maybe having the priest see the main character oogling another person in the church or something and using the pervert angle to try and coerce him to do his job for him.
Anyways, this turned into a wall of text I had not planned on writing. I hope you take it as feedback that I really really enjoyed your game and hope you keep working on it!
Last random thoughts about the game aesthetics: the main character hair kind of bugged me. It looks too shiny or silvery grey, which contrasts to the color of his facial hair. Something weird going on with the hair shader. On a positive note, though - I absolutely love that the clothes on the female characters don't wrap around their boobs as if they were vacuum-sealed. I've played way too many games that looked like that here and It's making me wonder if there are 3D artists out there who actually don't understand how cloth and folds work. Kudos to you (either for making the characters better than average, or for using better-than-average pre-made assets!)
TL;DR: Game is good. About to go check on the patreon and probably become a patron.
