Pixel Snake is a classic casual game. Players enter the game and click Start to enter the game state. Players control the movement direction of the snake (up, down, left, right) to eat the food on the screen, so that the snake continues to grow and increase the score. The goal of the game is to eat as much food as possible while preventing the snake head from hitting the wall or itself. The game will gradually speed up and increase the difficulty as the snake grows. When the snake head collides with the wall or itself, the game ends and the player's score will be recorded. The simple rules and easy-to-use features of the game make it a timeless classic.
