Although it is truly a pretty game, it is very much incomplete feeling. Not sure if it's just my copmuter glitching, but I didn't get an end screen.
There is no end screen, at the end of the track the camera just let the cart go on its way. You can restart with escape.
Why do you feel it's incomplete ?
Aside from the lack of an ending screen, which leaves me feeling unsatisfied as a player, most features seem half baked. The acceleration goes up exponentially at times, the signs don't pop enough, the score is almost invisible... A lot of testing and improving was clearly not done. This isn't an attack of course, it was a very tight schedule, but I am saying the drawbacks from the time limit are apparent
