You have an open area in Melon Playground where you can put different living things and abuse them anyhow you want. The game is casual and falls under the ragdoll/physics sandbox category.
Melon Playground's gameplay starts with selecting a map type. The next step is to use the left-hand menu to add different map items. Let me give you an example: there are fruit-based beings that resemble humans and are capable of movement, pain, and death (but you shouldn't feel guilty about it because they're just called watermelon- and melon-people). You can use a wide variety of weapons and objects to defeat them.
Feel free to administer acid injections, shoot them, hit them with various objects, revive them with another injection, keep an eye on their vital signs, detonate a bomb, attempt to reassemble them, equip them with helmets and armor, test their resistance to different attacks, and whatever else comes to mind. Restart the scenario or make a new one when you're exhausted.
In melon playground, you may test out various things' effects on the characters through physics-based experiments. The basic idea is the same as in any sandbox: you get to do whatever you want, with the exception that in this case you wish to hurt imaginary animals. Completely risk-free is Melon Playground. The game has maintained a spotless safety record from its initial release in 2021, and the APK displays zero positives in Virus Total. I don't see any reason to doubt its safety.
