The game is functional and has good art and sound. However, I found it got repetitive very quickly due to the absence of progression (ex: an improvement would be if kept track of how far you've gone so that you can set yourself a goal) and low obstacle variety. In particular, I notice there is never an obstacle that forces you to go into the left lane - you can just stay in the middle + right lanes throughout the entire game. I also don't understand how the theme of surprise comes in.
