Tractor beam was a little too weak, you had to be pretty close to the PLOW to move it towards anything.

Thanks for playing and for the feedback! Yeah, I wanted it to have propper inverse square gravity physics, but that means the force can be really strong when you get close or really weak when you're at all far away. If I go back to it I'll probably try and find a way of doing the force that feels better but less like real world physics.
