Does it sound like she could like me?

I met this new girl at work a couple weeks ago and we started talking and now I like her. The only problem is I can't tell if she likes me or if she just likes me as a friend. At work we always make fun of each other and once in awhile she'll hit me. We talk a lot and the other day we played bball against each other because she thought she could beat me and of course I had to let her win! But anyways when we talk she ALWAYS is smiling. And when I say stuff she sometimes kinda snaps back at me in a joking way. She asked if she could have one of my old sweatshirts so I gave one to her. I don't think that matters but I thought I'd say it anyway! Ha! But ya! I like her and I can't tell if she likes me.. I really hope she does.
