Some of these comments are pretty outlandish. There is no luck involved in this game at all and it's pretty easy, frankly. It seems like people dislike anything that doesn't hold their hand the entire time.
The concept is hilarious and the game is really fun, but I think it needs to get progressively more difficult. Once you are used to the feel of the top speed, you can pretty much play forever. It needs something to serve as a big roadblock after a certain period of time. This way, it becomes much more important to time your jumps to earn a high score rather than playing one run for two hours straight.
