I'm sorry to hear that you weren't able to play, but thanks for trying it out!
I had issues with resolution and the size of the camera when I built the game, but in the end, I was not able to fix it. That might mean that something important was cut off, so you were not able to continue.
The clamp was designed like that so you could see through it at parts underneath, but also see where the gripper is when the arm is not able to reach. If I had more time I would have made the smaller one disappear when not needed.
