Pick a path. That is what we are saying. Try to include everything and lose nearly everyone. Peeping/voyeurism can be hot so is having the MC fantasize in a dream. Also, you HAVE to choose either ntr OR harem. You cannot do both. The concepts are completely incompatible. You will lose far more potential fans with tags like bestiality, urination and scat than you will ever gain. The bottom line really is, make the game that YOU would want to play and stick to that but choose a branching path where the tags match. Choose your audience. There are die hard ntr fans out there who hate the whole idea of harem and vanilla content. Those same folks are often into BDSM, femdom and/or male dom but even that crowd is divided, only wanting to see certain aspects of those genres. The futa/trans lovers are also divided and only want to see certain types of that content. This is why I do not play games that are written by committee, where the author is making decisions regarding story based on his/her latest patreon poll. Give your fans choices but always write your own story.
I do make suggestions but will NEVER tell you what game to make. It's your game, your call 100%. I do share what I like and don't like but it's still up to you to decide. Just know that the more radical you try to make your game, the fewer fans you will have. As I said earlier, I try MANY games and AVN's from this site. I try games that have a few tags I don't like if there seems to be more content that I will like. Sometimes that pays off but more frequently those titles are quickly deleted.
At this point, I really need to play your prologue to have a better idea where you are coming from, friend. I withhold any additional commentary until I have actually played some of what you created. Again, I do not wish to seem overly critical. I've been around this site long enough to see what works and what doesn't. I am glad that you seem to want to make something different. I like that idea. It is good to blaze your own trail. I would simply caution not to try to blaze EVERY trail in the same game. THAT is a recipe for disaster.
Adventure ever on friend, Phat
