Hey, We didn't expect such huge feedback, and the website was made just for fun without any testing. We know that the webpage is clunky. Moreover, we're hosting it on a limited free Firebase tier. Sorry for the inconvenience.
This is particularly true on mobile where trying to use the back buttons once I finished reading became particularly confusing because mobile browsers hide parts of the URL.
