Thanks for the comment!
I wanted to use the parenting, but forgot haha. Tried it right now and sadly it breaks the physics on my grappling gun. I use a Hinge joint for the reel and it starts glitching when a strong force is applied and also apparently when the object it's attached to is moved using code instead of physics. Haven't figured out how to fix it sadly.
And the score, well.. I simply didn't make it in time, no score system is in the game haha. I'll be sure to implement it and update the game once the judging ends.
