Toddler fell off climbing structire

My 1 year old just fell off a little climbing structure. She fell from about 2' up and landed flat on her back and her head bounced when it hit. She landed on a mat but it's not very's one of those puzzle mats. She cried hard for about 3 minutes but now seems totally fine...wide awake, playing, no vomiting, pupils are the same size. Is there anything I need to watch out for or worry about?
