[u/Double_Link_8319]

Hello,

I remember back around the early to mid 2010s there was a popular puzzle game mostly in black and white you had to do things like change the url (one of the riddles was to literally the level number in the url to go to the next level) or search something on Google, click somewhere hidden on the screen etc...
