The dev said the main focus of the game will be harem with romance elements as you can see here:

He then starts off with a fully animated MMF NTR scene (because apparently getting cucked by just one guy wouldn't be enough), with a girl who
still is a romanceable character, which makes the "All other genres will be optional" a blatant lie and of course creates more voyeur scenes (only 1/3 optional so yet another lie, plus two of them are also animated which raises even more questions about the focus of the game...) than content with the MC...
That has nothing to do with lack of experience, that's creating a voyeur game with cuck elements and trying to "sell" it to a broader audience by throwing a few bones to the MC and calling it harem/romance.
Nothing wrong with that to be honest, the dev can do whatever he wants both in terms of content and advertisement, it's his game after all and no one is forced to play or support it.
But this is definitely
not a harem focused game with romance elements.
