I played about half of it (which is appropriate considering the content). The biggest thing that struck me was the effort the developer put in to make Sera cute and adorable at the beginning, seeking to get us emotionally invested in her condition. To then have her so horribly mutilated is almost sadistic. Perhaps this is what Guro is all about, and fans of that particular genre may love it but I didn't care for it. This site has taught me not to shame anyone else for what they like.
