This game has a lot going for it and definitely a solid concept. however I wish there was some type of lap recording as you were going around laps so you know if you are improving your time or not.
It would be nice if you had a popup saying how many laps where left or even when a lap was finished. It was a bit difficult to tell when laps where being completed.
There's also no real sense of how far ahead or behind you are compared to the other player. So maybe having a bar showing your ahead or they are ahead would have been nice.
