Corona editor has a physics editor. It is only mac and only supports 8 point
You have to decide, is a little money worth your time and the ability to proceed? Pay the money, support someone in the industry.
If you have trouble downloading the editor you can get them from here. I course do not own them all credit goes to the orginal owner. The only reason I am sharing is because the Mac version is hard to intall and I found a dmg version a while back. https://www.dropbox.com/sh/65byude9cuawb7z/AABSuBfuxtW7rlySo1hEsHwKa?dl=0
