Use arrow keys to direct the snake to the mouse for it to eat to increase in length by +1. Occasionally, a beetle will spawn, and if the snake consumes it, the snake increases in size by +3. And don't ever make the snake hit a wall, and never make the snake bite its body because if the snake crashes into a wall or bites its own body, the game will end immediately. Your high score is calculated based on the length of the snake.
