#multi-entity

Input.Pressed and Input.Down read a global input state, not a per-entity one. A component that reads them in its own OnUpdate samples that global state once per instance. With one entity on screen this is correct. With many non-networked instances of the same component, one keypress fires the action on every instance at once. Gating only on IsProxy does not help, because IsProxy answers whether the entity is replicated, not whether this instance should own the keypress. Gate the input read on genuine local ownership instead.
