OlliOlli was developed by Roll7 and published by Devolver Digital. It was a huge hit on PC and then later on mobile devices. In particular, the Nvidia Shield devices. The sequel to OlliOlli is OlliOlli2: Welcome to Olliwood. It is now live in the Google Play store. What is more unbelievable, is that the game is only $0.99 Keep in mind, that this game requires a controller, and more than likely, is only available for Nvidia Shield devices.
