How do you do it?

Hello fellow flash programmers!

I have a school project in which im supposed to create a game on my own. Basically everyone in senior year has a project of their own choosing and I chose to make a game.

Unfortunately no teacher in my school has any experience with it an neither have I except for at few basic tutorials. Don’t get me wrong there’s a lot of great tutorials but what I’m having trouble finding is how you get started.

What I would like to know is i.e what do I do first and what do I do after the first thing and so forth

Thanks in advance
Gurrlin
