Alrighty then,

I've been gaming on a girl in my class for 3, 4 months now.
To be totally honest, I was being a bit needy in the beginning (not having read the method and such).
We had a inside joke just between the 2 of us about eating half a chicken (we were wondering what they would do with the other half:p)
So we basically decided to go out and eat some chicken together sometimes, when I asked her first she had a meeting. A month or so later she asked me and unfortunately I had to teach martial arts (far away, so taking her with me wasnt really an option)

So I asked her again, if she wanted to go out and eat some freaking chicken with me(not using that exact same sentence ofcourse:p) She replied she was going on vacation tomorrow so she wouldnt have any time (she uploaded pictures and all that, so definitely true), but would love to some other time.

Looking back I can totally see I was being to needy, but now I feel like there's no way to change that around. Is there still something I can do?
I like this girl, wouldnt want to mess it up.

Thanks for reading,
Olivier

Sounds like the main way you've messed up, is not asking her out at a time when she can actually go out with you. That's easily fixed: ask her out. If something gets in her way again, be serious with her. Say, "Look, I really think we should go out. Priorities can get slopped around forever, but we both like each other, at least to the point of chicken. So let's do this! Saturday at 8 at BalBozo's?" I'm saying that you should be more direct with her. It may not be "total game," but it does DHV in that you have confidently asked her out, made a clear case that she should be going out with you, that priorities matter, and you've almost commanded her to go out. You put it as a question, but you did decide what to do, what the plan is. That shows some dominance and some spine. I don't think you can just turn around your previous AFC months of fumbling and suddenly be all negging and freeze-out and manipulative and stuff. It's too incongruous; when someone suddenly alters their persona, it reeks of insecurity and weakness. I think the gal actually likes you and you're both doing a bad job of making the move, so you should give her the benefit of the doubt and just go for it, stating the case from a position of strength.

Now, if she ducks you after that straightforward "lay your cards on the table" pitch, it's time to pull out game. First, don't talk to her for a week until after she gets back with "vacation" or whatever it was, then command her to go out. If she's not complying by then, then she's a "selfish broad" as Sonny from "A Bronx Tale" would say, and it's time to treat her accordingly. Don't plan on her, game her according to anything anyone has to say around here, and don't one-itis her. Work on other women. Make her jealous if you want to get into her pants. Demonstrate that you have other women going on and she's blowing it. It's sad when women respond this way, instead of to the straightforward strength and confidence you tried to offer her earlier, but not everyone is worth the value you offer. Keep your tallywhacker entertained while you look for better material.
