Fearing that he will be forgotten again, the friends try to trap him in their imaginary world by playing games with him! You are Croqui and you will win the game with your friends. An adventure game with an atmosphere like a picture book or a painting, featuring unique imaginary friends.

The characters and the textures of the stages use drawing materials such as colored pencils and crayons, and craft materials such as thread and clay origami. This creates the effect of creating a world that is picturesque and like a child's fantasy.

Although the adventure element of the game is mainly about finding imaginary friends, the mini-games with the four hidden imaginary friends offer another genre of games, such as shooting and puzzles.
