A few things about that based on what you wrote.
Although your initial game was succesful, the problem was that when you got into the theatre with her she was giving you value (IOIs) and expressing genuine interest in you. If your head was too far away you could have tried things such as hand holding or touching legs to initiate kino.
She was upset because you didn't reciprocate by giving her value in return and even worse expressed more interest in her friends and left her feeling neglected and ignored; now she is ignoring you.
As much as women love to play games with men, when they are interested in a guy it is his job to reward her intrest by giving her value and interest as well.
You came off as slightly needy by calling and telling her you'd talk another time then texted her back today chasing her down; if she was really interested she would have invited you to a party with her.
What you need to do is show her you still care about her without coming off as needy or just drop her and find someone else - your choice. As your signature says, "3.3 billion to go" obviously there is always a hotter girl out there and It really depends on how much you like her as a person and if she is easily emotionally replaceable.
