    // level description
    description: "Only darkness and disorientation items.<br>You need to eat <b>8</b> apples to pass.",
    // speed of the snake (tiles per second)
    speed: 10,
    // max length of the snake
    max: 11,
    // requirements of going to the next level
    next_level_requirements(snake){
        return snake.position.length >= 11;
    },
    // board (0 for empty cells and 1 for walls)
