Just gave Orbitz a try, and it would certainly be possible to create a game like that with these new features. When I created that little sample, I was actually thinking of another game I played ages ago that was on the iPhone, can't remember the name though. But I do love games that mess around with gravity (which is why I'm adding all these gravity related features!).
A video of a game TBHS3 created within GeoVertex for iPhone/iPod Touch and iPad - https://www.youtube.com/watch?v=-sKC-29wDRE It looks better now, thanks touchDev192.
I just want to show a couple of examples of some features people have requested, which will be possible with the next update: Firstly, a video to show a grapple hook implementation, using the new 'Create Joint' trigger as well as a few others: Creating these did require a bit of thought, and I may make a couple of tutorials to show the process for each of these as they can be a bit tricky to implement. But just wanted to show that they are possible!
