This comic was originally made viewed under a sheet of red acetate. This acetate would make all of the red ink disappear, making a kind of interactivity.

To recreate this feature, I have made it so you can mouse over the pages to remove a red filter. If you're on a phone, try tapping on the images.

...but just in case the gimmick isn't working for your device, I am also putting the original pages here, too.
