Smash & Stack
Drag back like a slingshot, release to fling one projectile and topple every stack on the table.
Set angle and power with one drag, release to fire a single ball that must knock every object off the platform.
Drag back from a cannon to aim and power, release to fire.
Royal chaos destruction — castles, jars, towers crumble under one perfect shot.

It's almost exactly the same' — explicit confirmation of clone saturation ↗Monster KnockDown : Slingshot — another clone in the same slingshot+knockdown space ↗
