Cool game! The first time I didn't make it, but on the second try I reached the airport :)
I really like the camera perspective and the sunset visuals. The new ending is also very nice.
I think you could try and improve some smaller things, like:
- visible lanes
- more feedback (animations and sounds)
- adding environment models
And then you could extend the gameplay:
- more levels, increasing difficulty
- different obstacles
- different goals to achieve
However the game already offers a short, but fun experience and you might want to keep it like that.
