Increase Max Health

Double Your Points
Try to grab gems and junk when you are wearing a special suit. The points are multiplied by two. The grapple arm suit has the longest lasting timer, so use that to maximze your score when grabbing gems over long distances, but in a pinch, any suit will do.

Look And Don't Run Too Much
There are 2 bonuses you need to watch for in order to get more points - one is a blue bug that hides fairly quietly in hard to spot areas. All Rayman needs to do is look at it in 1st person for a while and earn points.

The 2nd bonus is a reddish alien flower that runs away if Rayman spooks it by running, dropping, or attacking. If you manage to sneak close to it, you can earn a lot of points.
