Great game, definitely recommend it. It kinda bugged when it said 6 AM, but I figured out how to fix it. And I got hidden ending on my first try so win-win!
So there is an icon where the text comes in, right? I was playing in the browser so you have to scroll right to see the icon. Then when it starts getting close to that time where it says 6 am, that's when you start to click it. Make sure to do it slow, don't rush. Not sure if this will work for you but try it.
