There are 36 main levels in Rayman Jungle Run (more on the extra levels shortly), and they’re broken down into four different sets. Each set revolves around a specific move, including jump, fly, wall run, and punch.
Taking a heart will give you a second go if you get hurt.
Giant floating gold coins can give you a bunch of Lums in one go. Just try not to get hurt before the coin explodes.
Jumping the opposite way off a vine or letting yourself fall down certain gaps will result in the discovery of hidden Lums.
Worry more about finishing a level before finding every Lum in it. This way, you’ll have a stronger knowledge of where they’re located when you play again.
Killing every enemy you encounter isn’t necessary. In fact, sometimes it’s better to try and just avoid them. I’d be singing a different tune if they had Lums in their possession, but they don’t!
Try and remember exactly where the Lums are on each level so that you'll be able to collect all 100 in one go.
