Hug after first date?

I took this girl out to dinner for our first date. It lasted about 2 hours. We talked the whole time and got to know each other a little better. At the end we had a small snowball fight. At the end we hugged said hood bye.

Does a hug mean she didn't enjoy the date? Do you think there is a chance of a second date?
