This one is a true shame. Story-wise, it has been one of the most interesting games on this platform. I absolutely loved Inanna and the big background story, although I would 100% have to replay the game to remember all of it.
The Intoxicating Flavor was one of the first games here that really showed me that you could write a good and interesting story in an adult setting. I remember when I first played it, there wasn't all that much content. It started slow and felt a little robotic. There was sex with the mom already, but I wasn't hooked and decided to try it out another time.
The next time I tried it, Inanna was there, and boy I was sitting in my room at like 4 am just flying through all those lines of text while they sat in that mind palace which was an awesome fucking background. And man I was hooked. Since then I have always sat out an update or two just so I could enjoy a chunky read.
As to why the game never got popular, I think there could be many reasons, and I haven't played for a bit now because I've been waiting for the next update (which will unfortunately never come, it seems). But I want to list my thoughts here, maybe they help.
The sex scenes: I think they are a big reason why the support was fairly low, or lower than it should've been. They were, at points, robotic and the moan audio was the worst I have ever heard in any game. It's super low quality, not sexy at all, and makes the game seem cheap, which is weird because the story / renders are top notch quality. The angles and buildup were kinda lacking "spice". It was like you pressed "sexy pose" 1, 2, 3 and put them together and were done with it. They were lacking in passion and eroticism, which may be a cultural thing because I notice the same is true for other eastern european developers.
The beginning of the game: I have no experience in developing games on here, but I think the game had a rocky start. It starts really slow, with just 2 or 3 hot girls to look at while nothing much happens. There were also really small updates at times which made me wonder what's going on - maybe motivation was lacking, or 'milking' had started? I know it's not true, but those were my thoughts at the time.
The story is niche: I think not many people are interested in long winded explanations of a deity on how the world came to be. Personally I am, but many others won't be. 200,000 words is a whole fucking lot. If people came to fap to hot redheads, they will get frustrated at some point, especially with how long it took for the elder daughter to finally get some action.
The youngest daughter looks weird: While I really like her character and the dynamic she has with the MC and her sister, her eyes and mouth were off-putting to me at times. She looks possessed, and not in a good way.
MC's powers are useless: It's nice that our guy has powers and can basically do whatever he wants like a half god (I cannot remember what exactly was going on with him). He worked out twice and gained an incredible amount of strength. He's super smart and can do other shit. But.. he never gets to use it. He's just walking around in his flip flops and tank tops and procrastinates 90% of the day until he fools around with either the mom or eldest daughter. That's it.
Of course these are just my personal thoughts and they might differ vastly from how other players feel, but that's what I think was "wrong" with the game and made it less of a success than it was (so far).
Hoping to see you return some day, dev. I really enjoyed your game a lot and I wish you nothing but the best in life.
