If you’d like to keep your upcoming LD entry a bit more organized, I’ve written a quick game design document template for the purpose.
If you don’t know what a game design document is, you can check out the Wikipedia entry. Although this one doesn’t fit that bill exactly, it’s designed for use either by a small independent team or the infamous one-man army. With the text blurbs, it also serves as a bit of a game design tutorial.
Anyway, you’re more than welcome to use it as well if you think it’ll help you. It never hurts to be a bit more organized, eh? ;D
