This app is designed for children in the year 2100 to play.
Those of us living today can pass our memories on to future generations through images, sound, and text.
And now, with the power of AI, we can share those memories and stories as a small game.

This quiz is, in a sense, a time machine that people living today leave for the children of the future.
It is a game where people in 2100 can feel as if they are riding a time machine and experiencing theirgreat-grandfather’s story.

And by now, you may have noticed: this is a story-quiz built from the creator’s most exciting moments in life.
Choose a photo, tell a memory.
Yes, the most important player in this game is the creator.

It is a game-like gift, like a letter to the children of the future.
