Hello,
I’ve just started coding a simple game and (apart from how I am excited with Corona) I have found a significant problem - probably that others have also.
I was learning Lua using a book from 2013 and they use storyboard scheme. After spending many hours codding, I have found on Corona docs that storyboard has been replaced by composer and… had to start learning again :-/
The other issue is that most materials (books, docs) discuss individual elements (Lua syntax, sprites, sounds, interface etc.) and there is difficult to get the vision how to piece together all that blocks to get an app.
I know, that every game is diffrent, but what I mean is to show a basic scheme - start page, menu, game, levels, terminating etc. to see how the project could be build.
Now I am looking at endless runner game on Corona’s blog - it is great, to analyze, but… to complex for first time
Would be wonderful to delve into similar, more simple project and draw a path to own projects 
Drawing on other not always should be cloning. It is also good way to run own imagination and creativity 
Such “reference” game, regular updated, would be very helpful for many starting coders.
Best regards!
