Pretty fun, but the concept gets boring after about a year.
The game is simple, you just swipe the screen of your device to move your character and avoid obstacles like trains, bushes and signs. It's not that violent, except when you get hit by a train, which is not gory or anything, you just fly up in the air. You can earn coins to buy characters, and the coins are easy to get, so there isn't a need to make an In-App purchase for me. There are constant updates, with limited time characters and scenery, which makes things interesting although after about a year, in my opinion the concept gets old, but for the most part it's pretty fun to play.
