Hey Ventilator,
I've been testing Newton Physics as well. It's damn cool. He is a friend of Dr. Jelly and myself. He made it from scratch a while back ago. We showed him Gamestudio and he wanted to see if it could be ported to it. It took him a day to do it. He is motivated by the fact that there isn't a good physics solution available for the Gamestudio masses and he's having fun doing it.
