This window is a window into the universe where little people live.

When you draw lines with a light pen or stamp with a light stamp, lines and stamps are created and the little people begin to play.

The lines give the little people various powers in their world depending on the color of the line, causing them to, for example, accelerate or bounce.

Stamps start to move in the world of the little people, giving the little people various powers depending on the type of stamp.

The little people will play more adventurously if you, together with others around you, draw a big picture or use many stamps. Create a new world for the little people and give them various powers.
