I want an existing mobile game, with a small change.

Hi all, I have a very simple request, that will not take long from you. If you have already designed a nice game for Android, I want the code to publish on google play. Changes: 1. I want to change the design of the main character to the design that i will give you. its only one photo without animation. just change the source of the photo in the code. I prefer a SIMPLE AND FUN 2D game or a FUN PUZZLE game and that it will look modern and clean please. 2. I will provide a App ID for RevMob and i want a small ad banner in the game. 3. change the name of the game. VERY SIMPLE :) Please send me a link to your android game and show me the game before and Iwill choose if it is the one that i want to make the change. Thank you very much! my budjet is around 50$ - this is a fast job if you have a good game allready. Yaniv
