click the green flag then select the type of game you want to play. after selecting the difficulty the use the right and left arrow keys <- -> to move. in tree mode you dodge trees and in flag mode you must go between the two flags, if you don't, you loose.
I made it using the old skier images(thank you Google) and I just made the other images. not my most complicated game, it took about... I'd say about one and a half hours. I hope you enjoy. please check out my other games at http://scratch.mit.edu/users/hiccup_gaming/
