I'ma have to agree with yarow here. The fatphobia is not only in the spin-the-bottle scene and Panzer IV Jack, all of the girls are borderline anorexic and conform to socially constructed beauty standards. That's by far not the only problem though. The game is also ableist, why can't the player be with a girl in a wheelchar for example?? As yarow also mentioned: skin-color. Not only for the MC but also the other characters. Why are so many of them white? Also the whole setup of the game objectives women, just say the right thing and they'll all fall in love with you and don't even care that you're cheating on them all the time. Only a privileged, heteronormative, sexist, racist, while looser could have made such a game.
Since not everyone will recognize the sarcasm, I'ma say that it is sarcasm here. I respect Caribdis's games to much to actually be a troll in his comment section.
Once in a lifetime is an awesome game already and Caribdis surpassed themselves with Eternum a hundred times over. And neither Once in a lifetime nor Eternum are bigoted in any way.
