I got lost and ended up at the opening page 5 slides in. Also the 'tap to continue' was half off the screen in iPhone X. This feels like a new version of those scroll jacking sites from 2010.
A shame that having plain paragraphs and pictures does not work (Android dropped support since N).
Commenting on the design, as a slow reader and non-native English speaker I felt annoyed at having to read against the clock ticking away for each slide (or alternatively, having to click 'pause' again for each slide individually). I hope whatever package this page is based on changes their default settings in future releases.
