You have to meet your girl friend at the bus stop. Meet her before the time runs out. You will earn more points if you collect the bouquets on the way. Do not hit on any vehicle and obstacles, then you can't play further. Reach the girl in the bus stop to kiss and move on to the next level. Finish all the levels to win the game.
