y mejoras.

Este es un juego de serpiente en el que el jugador controla una serpiente y debe comer la comida para ganar puntos. Además, hay enemigos que se mueven alrededor del juego y si la serpiente choca con uno de ellos, el juego termina. Hay tres niveles de dificultad en el juego que influyen en la velocidad y cantidad de enemigos. Se recomienda jugarlo en un dispositivo móvil para una mejor experiencia de juego. ¡A disfrutar! 🐍🍎👨‍👩‍👧‍👦📱
