Hi, I'm pretty new to all of this stuff and could really use some input

I've been friendly with a girl for a few years, kind of an acquaintance more than a friend - we've never spent much more than 10 minutes together. At the weekend we met at a party. I tried to run game on her and it seemed to go well, a few IOI's etc, however due to my lack of experience I know my game is not solid

Anyway I invited her to my house to watch a film, back at the house we laughed and enjoyed the film through the night. However besides a few elements of game including kino I didn't make any huge attempt to escalate. The main reasoning behind this was that I'd had a few drinks and she was sober - i didn't want to seem like a drunk leach the first time we were ever alone together.

However now after spending time with her, I have found I like her and would like to progress things. But I'm not sure if she feels the same, or is very trusting of people she sees as friends.

What is the best plan of action for when I see her next?, try some elements of game - in which case what sections should I try? Or should I just be flirty and friendly and lead to suggesting meeting up again?
