Please feel free to play because it is a game that everyone can easily do.
First of all, please choose the difficulty. There are three kinds of difficulties.
First of all, please remember tooling when the game starts. The kind of the tool that comes out increases as the difficulty goes up.
The octopus ball enters the state that the tool is not seen if the remembered time ends. Please choose the same octopus ball as the kind of the tool that comes out up.
When the time left vanishes, it is game over.
