ok, im new as well. heres what i do. I start off by creating all of my pictures (buttons, sliders, etc.) go ahead and define them before you even start actually creating your game, this will speed up your progress later because you dont have to keep going back and forth from your game to yor paint program. Then start creating your levels (if you are using levels). then create your models (if you are using models). If your creating a 2d game, you probably wont need levels or models. Then start actually scripting your game. Hope this helps!
