Starting a fighting game

[Kofman]

I'm starting a fighting game in QB, and building my first ever real engine. Not an advanced engine of coarse but it will be the first program in qb that will have one and not just be plain code to make the game play. While I believe I've now learned QB I haven't had enough experience with game creation. What are the steps I need to take to begin. I haven't wrote a single line of code yet and I am listening to what I should first do.

Game Features:

• it will resamble street fighter
  the charecter will hopefully be able to jump and through basic moves
  eventually or near completion I might give each charecter a special move they'll be a ble to execute.
  the game will start of with one charecter and several bosses
  The game is just that. I will post up the UI for the game later
  The game will have a deadline by June.
  those are all the basic requirements
  

Please help me to get started on this game. I want it to be a beuatiful game with great controls and most of all AI. I need some sort of guideline and I'm open to tips from the experienced.
