I played "(Don't) open your eyes" 2 days ago. I loved it so much. Just the vibe it gave off. You don't see such a scary visual novel every day. And it has a great story too. And it has voice acting. The fact that that all is all made in 30 days is insane to me. After that game I decided to check Radio.signal out. It was so worth. I enjoyed every second of it.
(I recommend anyone who hasn't played these games to play it asap. Such a masterpiece for free is something you dont see every day.)
!!spoilers!!
I thought that the voice was an a$$shole and I hated every single thing about him. Until I got the ending were you muted him. When I heard him plead I realized that, he just wants someone like him. Someone who has a messed up life. Not because he loves that life. But because he cant forgive himself and think he is born to be evil. And since the MC was like him and known him since childhood, he wanted the MC to be a "monster" just like him. He feels like he cant be forgiven and doesnt want to lose the only person who relates to him. So he tried to convince the MC to think he also can't be forgiven. I mean this is just my theory but I think both the voice and MC deserve better and can always change their life. The MC was forgiven by his first sin. But who is there to tell the voice he is forgiven? The MC would have probably not made it if it wasnt for "his first sin" cause he told him he was forgiven. I think both of them deserve happiness at the end. It's just my theory of course and I don't know what the voice is actually thinking. Or who he even is.
