Twin Paradox (双子座のパラドクス) is another Cotton Software title. Why’d I play it? Mostly because its predecessor, Sekai ga Owaru Basho to Birthday, left such a strong impression on me. So even though the character designs are still shit as always, I was willing to give it a go. No other reason — I just wanted to see a story that could stand shoulder to shoulder with Birthday. That’s all. But before I get into the game, I want to talk about something else: the science and pseudoscience elements in stories.
