I have been writing a lot of tutorials on my site
http://howto.oz-apps.com these are generally quite framework neutral and more lua based, with a slight hint of samples from another framework. Never the less, the concepts are stil Lua based and apply in learning, so if you are starting out and need to look at some reference material to learn using lua in a framework/game setting, then head over to
http://howto.oz-apps.comThe topics are from Memory Management, Function Libraries, Booleans, Tables, Reducing the size of your final app, etc.
