Good Dogs is a fun little time killer. It’s an infinite runner where you pick a dog and try to run through the park for as long as possible. It’s connected to the popular WeRateDogs twitter account (which you should definitely check out). There are seven dogs to collect, stuff to customize the dogs, and the developer promises to change up the park on a monthly basis. Truth be told, it’s not much more than a time killer. However, the in-app purchases are for in-app customizations and not a gem system. It’s kid friendly, adult friendly, quick to play, and free.
