This was on the Safari browser on MacOS on a desktop computer. When I switched to Firefox on Mac the problem stopped...so you might just want to note that Safari may not be supported.
Once into the game with the lower menu (I think it had options like "Me - Them - Facts" ?) attempting to click on one of the lower menu options made the words seem to 'race off the side' like it was an animation that played wrong and the words disappear. This caused nothing onscreen to be clickable further until the browser page was refreshed. The game would load again, links in the story were clickable but if the menu is clicked the glitch repeats.
