Thanks for the feedback! You are not mistaken in your feelings - the properties are in fact the same ball or not! This was due to time and my own limited knowledge about the built-in physics engine that GMS2 has. It was fun to try a feature I haven't used before but in the future I will stick to coding my own gravity and physics. The nice thing about it though (if I could have gotten the rest feeling better) was things like the box rotation and slopes were very easy to implement.. too bad we did not make much use of it!
