Yes, after hitting and/or holding spacebar, something happens, or you change to a new year. Sometimes it's just pictures with some text of whatever was important at that year, sometimes it's animations, sometimes stuff you can interact(?) with. In 1995, there is an old Desktop-PC with Windows 95 booting and starting a modem-connection, and you can type on the keyboard. Pretty pointless, but kinda neat.

So it doesn't work on phones apparently.

There is a "hold to rewind" button on the bottom in mine (ios).

Ah thanks, it was just my ad blocker who blocked it.

What are we supposed to do, and what is supposed to happen?
