Kick the Buddy is a stress-relief toy in game form. There's a ragdoll, there's an inventory of increasingly ridiculous weapons — from boxing gloves and grenades to lasers and industrial machinery — and there's no objective beyond seeing what each one does. Buddy is indestructible; he always comes back.
You earn currency by playing, which unlocks more of the arsenal, which is the entire progression. It's crude and it knows it, and it's been enormously popular for exactly that reason.
There isn't one beyond experimenting — it's a stress-relief toy. You use weapons on an indestructible ragdoll, earn coins, and unlock more weapons.
It's cartoon violence against a ragdoll with no blood, but the whole premise is hurting a character, so parents may want to judge it themselves.
