How do I get 5 perfect jumps directly after an island jump?

After you leave one island you have to land perfectly on a hill of the next island and you should see the (+points) at the bottom of the screen. You have to do at least 5 of them in one play through, but not in a row. Island 4 is maybe the hardest island to get a perfect jump because the hills are very steep.

Some times you may think you have done a perfect landing but it wont count due to the fact that the game is very sensitive on jumps. For example: You land on the tip of a hill and continue to slide down the hill. If the hill is large enough, when you jump you still get the points but it wasn't a perfect slide.

Keep at it and you will get it soon, its a fun game.
