Rescue or Shoot the Girl

One of the villagers were invaded by some unkown guys and they kidnapped the innocent villagers,threatened that if we didn't go there to rescue them,those villagers will be dead in no time. The only way to rescue there would be by shooting the rope.There's no way that you can get any closer,the only weapon you have is the bow you practise every day. You have to save those innocent people by shooting the rope and not hurting them. Remeber, if you missed the shoot, you might kill the victims instead of rescuing them. You might need to make use of some items to reach the goal,the gas barrel and tnt barrel could explode and destroy other items around it.The magnet could drag your arrows towards it.And some arrow has variable shooting force,so you have to shoot at the right time.
Time is limited,and it matters life and death,try to rescue those people as soon as possible!
Time is up,if you take too long,those people would be suffocated. Try to make use of different things to help you.
