Hi all. Yesterday I watched a live presentation from Trey over at BuildBox.
Note: I am not pushing BuildBox or saying you should use it.
I am saying you should watch this video: http://www.publisherweekly.co/replay/
They covered some valuable points when they took apart several apps and then improved them to make them better and more salable.
These same steps apply equally to any games, including those made with Corona. I think new and old developers alike will take away a few good points.
