I am pretty new in game development - on Android platform and thinking about one-man game development. I know I can't professionally do everything such as graphics, sounds, and music but I think I can worry about them later once I finish its coding.
My current road block is setting up game design process. I've read some books and lecture notes on game design such as A Theory of Fun, and Book of Lenses, but still not sure about the process.
Of course, making game ideas is kind of separate process in long term so I can assume I already have an idea for a game in this question. But for conceptualization, what can I do? I think people usually make a design document and story boards for this. But for android platform, I am not sure design document is necessary - maybe design summary would be enough. In that case, would story boards (or doodles of game screens) be enough for design process? What else do I need to do in the game design?
