Well, this game is rpgm,so thats usually a big NO NO for starters. Sometimes some fo these games ofers something that others do, sometimes don't, and this one is one of those that don't. Its 4:3 aspect ratio, and that is banned from media since early 2000 i think. Having less pixels to render we as players dont get anything in return like increased overall resolution and renders look crappy. Crappy and 4:3 is not a good thing.
As foir the game, there is nothing new: Bitch femdom sister, loving and secretly a massive whore younger sister. Plotwise there is soe sort of unexplained thing going on and the feeling is that the game is Beta, cause many events are short and have a disclaimer at then end of content, so the game is fukll of those disclaimers. The dev comunicating in any way with the player is a 4th breaking, and we dont like those, even if the story is so silly and the events are not even possible to happen in the real world like 5 guys gangbangin a girl in a train and nobody even notices it, like they were in a parallel world. ITs 100% brainless fantasy, so shut your brain of or you will die of cringe.
As for the gampley i dont agree that is grindy, i think is pretty average, and grind is not the main issue since you need like a cycle of 4 interactions to evolve relationship status, and you can get easily 2 every day. The issue are the half baked events, and maybe some events not triggering like the videogame match (i couldnt win a single time).
The issue are the disclaimers popping everywhere but in some events are not popping and it makes you think there is still content available, which unfortunately is not the case with those.
One good thing that has is decent "sex" scenes with the limited resources it seems to have, thats why its 2 stars and not 0. Still i dont know if the will offer that little extra of visuals, cinematogrpahy or whatever to make them really fappable. If that was present, even with this low amount of content i would give a "good" rating, but its not the case, and i think the game is not new.
