The game is really good for sure but i am not here to talk about the sex as the story is much more important in this case. I am here to argue against (spoiler alert) the idea of having to choose between the life of Melissa or Megan.
There should be a particular set of choices you can make, especially after the foresight of watching how the story ends, that prevents this disaster. I get the life lesson the writer tries to teach by the closing lines, however i find it hard to believe there is no path to saving both girls in a decision based game. I mean the girls aren't even that heavy, you should be able to drag them both out especially with the adrenaline and the athletic trait. Or, as others have said, dying and saving them both or your bro dying to save them would be a fair exchange.
I was completely faithful to Megan in my first playthrough and i didn't even have the choice to save Melissa. It was not because i didn't like Melissa but because, not knowing much about the game, i was saving her route for last, since i liked her the most. Now i know that choosing her, i will be killing Megan. The story should be having a ton of replayability but with such a fixed heartbreaking conclusion it kind of wastes its potential. I just can't accept such a predetermined ending in a game so full of choices.
