As a big fan of OutRun, specifically the SEGA Master System version, I really enjoyed this.  It shares a lot of the same vibes, and though it doesn't look quite the same, it does craft some of the most beautiful scenery you can forge with a Game Boy Color.  The challenge level is WAY down from the versions I've played, and as far as I'm concerned, that's only a good thing; it's a nice drive through some breathtaking vistas.
