Dear Talented programmer, We are currently looking talented xcode programmer to bring our game to the next level. this far we have start the project and it goes forward quite easily. There is missing some features, still, which would mean: a) Enabling our Settings page b) Enabling player to authenticate against Facebook (OAUTH) c) Enabling user to share the information when (s)he as managed to complete one level -- User should be able to press "facebook" icon, so that it will share the successfully completed level information: -- Information should have "level #, level name, time (how many seconds it took to complete the level), how many stars user got from level (1-3) -- In the wall posts, there should be also the hero character presented and the amount of starts user got What comes to IAP, we are hoping, that you can help us building In-application purchase functionality to our application. We have idea already how to do that but not 100% sure how it should be done, so in that sense we are hoping that you have already completed projects which has been included this kind of functionality. We count on your expertise!
