I may have fixed it, if you'd be so kind as to give it a try and see if it works for you and then let me know if it is still broken, that would be appreciated. I tested on my own phone and had the same issue (only it showed 5 slots, but very zoomed in lol). The issue, I think, was with how the mobile stuff was set to appear through itch. It was on "default" and I have changed to to "portrait" instead. I imagine you may need to exit the story and then go back in, but I'm not positive.
