Melon Playground is all about experimentation. Players are placed in a simple 2D sandbox where they can spawn characters, weapons, vehicles, and various objects. Once placed, everything in the world reacts according to realistic physics. Characters have ragdoll bodies that respond naturally to gravity, force, damage, and environmental effects.

The controls are easy to understand, making the game accessible to new players. You can move, rotate, freeze, or activate objects with simple actions. Time manipulation is also a major feature, allowing players to pause the game, slow it down, or speed it up to closely observe how different interactions unfold. This makes the gameplay both chaotic and strategic depending on how you choose to play.

There are no rules forcing a specific playstyle. Some players focus on building machines or structures, while others enjoy testing weapons, medical tools, or environmental hazards. Every session can be completely different depending on your creativity.
