Really fun and original idea !
Even though the score system seems totally random, I had a lot of fun trying to cut hair as good as I could (which often ended up extremely badly)
I don't understand what the third tool does, especially with the different settings (yes I should have followed the tutorial, but the rest felt really intuitive)
I'm curious, did you use something special for the physics or is it just a lot of ropes made with the engine's physics system?
Well done!
