Embark on an exhilarating journey in "2048 Serpent 3D," a captivating arcade game where your objective is to skillfully maneuver a serpent constructed from a chain of vibrant balls. Your primary mission is to strategically collect scattered balls, aiming to merge them into progressively larger spheres. The more successful merges you achieve, the more your serpent will grow in length and formidable power. However, a crucial element of strategy lies in discerning which balls to collect; only those that can harmoniously merge will contribute to the formation of your ultimate, perfect serpent. Be ever vigilant, as a menacing black mist relentlessly pursues your creation. If your serpent's tail strays too close to this encroaching danger or becomes excessively elongated, it risks being engulfed, resulting in immediate failure. Each subsequent level intensifies the challenge by accelerating the serpent's speed, transforming the game into an increasingly demanding test of reflexes and strategic planning.
