PetRun: An iOS Game developed by a 13 year old! PetRun, a side-scrolling endless runner, has just come out. This is my first app on the app store, and I am sure that there will be many more apps to come! PetRun is free, so be sure to get it! Check it out at www.appstore.com/PetRun As this is my first app, I am excited to announce that in less than two weeks, I have received over 3000 downloads!
