I was working on a game but i stuck on the way here is the idea of the Game, is a platform game, when the character is ruining on the platform and there is a hole or obstacle on the road the player will click a button and the character will jump up and stick to top roof platform and continue ruining on the top roof platform and while is on the roof runing if the player meet another hoe on the roof the player press the same button and character jump down on the platform ad continue, if the player can play the game very well it continue like that, and score high but if fail and jump it the hoe either roof or platform then the character die and game over screen pop to restart the game here is a sample picture link for more understanding http://www.mediafire.com/file/fu0l611y2 ... sample.png i will highly appreciate any support
in platform behavior you can change "gravity into -x value" to obtain the stick top roof effect, adding some edge sprites that changes gravity when you overlap them and jump when you want to invert all, sorry my english <img src="{SMILIES_PATH}/icon_e_smile.gif" alt=":)" title="Smile">
