You can not believe me, but I really hope that I'm wrong. I like your studio for creating "Our home" and thought that you can resort to puppet accounts makes me sad. ( Even if you did it, please don't do it again. ) This is my last post about your possible puppet account because here I already said all what I wanted to. So don't worry, I won't be nagging you about it anymore.
"Just because someone is trans doesn't mean they are fake". Of course I agree, there is no 100% guarantee that the user isn't really a transgender. Although it was just one of factors (transgenders are rare in any country, so statistically speaking here is higher chance to meet a cisgender who pretends to be a transgender for some reasons) that made suspect that it was puppet account. Aside from suspicious date of both account creation and the post itself (plus fact that it was the only post of said user) at was also good contrapost to my critique of the game, where major aspects of the game that I critiqued were mentioned and given big thumb up. Of course there is chance that I was wrong, but considering all chances it looks improbable that it was genuine fan account.
"we're too busy for something like that, even if we wanted to."
It doesn't take too much time to create a puppet account and write positive review of your game. Besides, games with positive reviews are good for your portfolio. You seem to work as non-profit for know, but I guess you hope to gain recognition and then become commercial game-making studio. But again, I would be glad to be wrong.
