Realistic human and item behavior is brought to life via the game's physics engine. Many physical phenomena, including gravity, friction, collision, and others, are visible. When objects or characters are damaged or destroyed, you can also observe blood effects and damage visualization. Melon Sandbox's gameplay begins with the player selecting the map type they choose to play on. From the left-hand menu, you can then add other items to the map. For instance, there are fruit monsters that resemble humans and possess the ability to move, take damage, and perish.
