If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
Just have a look at this bike rider (steve) and remember his hair style & dress worn by him. You have to make him to kiss his lover Jane ,by clicking on the bike. Attain the kissing target before the estimated time gets over to play the higher levels. In the 1st level if you kiss the wrong person, the game gets over. In the 2nd & 3rd level you got to fill the kissing target when no one notices you. If noticed, the game gets over.
