While many of us may be lucky enough to have all of the entertainment we want right at our fingertips, what do you do when you have to make your own fun? You could inadvertently dabble in 2D platform design, for one.

Reddit user Juankestein has posted images of a paper "Game Boy" that he made when he was nine years old. As you can see in the image above, it's a small piece of rolled up paper that unravels to show five hand-drawn levels of different themes, which you presumably play by moving your finger along while using a lot of imagination; it's a very simple version of how some 2D platformer levels were initially designed back in the day.

You can see all five "levels" below, and we certainly hope that enthusiastic young gamers of the current day may still produce the occasional charming piece of hand-crafted art in place of playing the real thing.
