This is a game called ”Eat to Survive.” In this game, you control the movement of a snake and try to eat as much food as possible to score points. The game is played on a canvas element, and the controls are based on arrow keys. The game ends when the snake hits the wall or hits its own body. The game starts again when the user clicks the ”Start Game” button. The score is shown at the top of the game screen, and the game over message appears when the game ends. The emojis are not used in this code.
