I do like these sorts of games that are really quick to get into playing, and you can restart really fast when you die. So it's addictive in that way.
I think that if you had some kind of warning countdown before it switched segments, it would be a lot more enjoyable. I also think that if you could switch between lanes a little bit faster / more consistently, it would go a long way as well. Making it fast and hectic but giving the player more control could make this a really solid game!
