Does it damage the enemies?
Never tried myself.
I have thrown a stone. It does damage them, but not much. Only around 20 points. You just move an object like a chair, stone, garbage, whatever so that it passes by, or lands on the enemy.
It works, but is not very effective since it is slow, low damage, and takes some practice. I can only hit them about one in four times, and I practiced for about 5 minutes.
