I am with Aelkirie, I got confused why clicking left mouse button wasn't doing anything. I now realize why. If I had an indication where it will grapple would be nice. Otherwise, let me click left and watch the rope be too short. I will learn better over time if I am allowed to fail.

I really love most games that has grappling physics, including this one. The frustrating part is the fact that at first, I was wondering why some of my mouse input is not registering, then I realized: The game won't let you grapple if the grapple is out of your reach. It's frustrating that I'm not even allowed to shoot a grapple and miss, instead the game just refuse to let me shoot anything, making me wonder if the input was not registering.

If you die while grappling, there's a chance you get no clipped outside of the map.
