add ad codes, improve the movement of football and add goal keeper in the 3d football game

bid very seriously so time will not be wasted of us both. I'll not talk about your bid in chats and there is no extra work required, other than mentioned below. the details of below work will only be shared with the selected freelancer only. you should use Unity3d 5.5.0f3 for this work. while working on it, keep in mind that this game is already compatible with android and iOS phones and tablets, ok. so keep it compatible with these devices. This game is already on the play store but this is not running as needed it to be. [login to view URL] 1. You have to add or replace the ad codes in this game for banner ads, interstitial ads & Rewarded Video Ads 2. You have to improve the movement of the ball to make it look real when it move. 3. you have to add the goal keeper in this game which is already in the source code of this game, all you have to do is to make that goal keeper functional in this game, so it'll be applied as required for each gameplay (Time Attack & Arcade). ok once this work will be done, the next phase of this game's work will be started, ok.
