Celestia.io is a game that is similar to Agar.io. You will control your planet-like character around the map to eat food for growing your size. Try to demolish the bigger players to turn them into your food, and attempt to defend yourself from the bullets of other enemies. If you become way too big, you will move at a slower speed, which makes you defenseless to some assaults. Hence, you must use your tactics to run away from them, or else you will die. The main objective of the game is to become the best player of all!
