Reminds me of the Outrun series.
I admit that the game has become a lot better than its father but I have the feeling you have gained inspiration from the Outrun series. The mulitple ending and areas are similar to the series but the streak of origninality from you mulitple vehicles and not just Ferrari's dominating the whole game.
I hope, if you do decide to create a third, that more original ideas will come to mind as the sense of you copying the series in this one game has deducted you one star although the overall is still 5/5.
