What part did you help with? Was this written in AS2 or AS3? How long did it take to finish this? Who else helped make this? Answer all of these questions and you can easily prove that you were the developer. Or, you can implement the highscores API.
Hmm....I think that this could be turned into something really good, although right now it is missing something. It's too easy to get through all of the obstacles and win, maybe make it harder? I liked it, 3/5.
