Yup, I can confirm the above graphical error. It’s not nearly enough to make things illegible, but it’s certainly noticeable. I’m also using an AMD card. Apart from that, I’ve seen a few spelling/typing mistakes here and there, but I didn’t bother to write down the details (though if they’re appreciated, let me know where I can send a report for these minor issues, I’ll keep an eye out for them).
Enjoying the story so far! My experience and familiarity with visual novels is limited, so at first I was disappointed with the lack of interactivity, but on the other hand, I wasn’t expecting so much story content. And I just had to get used to the game mechanics, wasn’t expecting the interactivity to be done solely through use of the phone. I’m currently on chapter 4.
edit:
I was also able to skip the movie, but I also had some saves available.
