NinJump Hints for iPhone/iPad
Here is what you get from obtaining enemy abilities while climbing up the wall,
Get 3 birds and you will grow wings that fly you up the wall getting you more points quicker.
Get 3 squirrels and you will become a giant squirrel jumping from wall to wall gaining a large amount of points in 5 seconds.
Get 3 ninjas stars and you will be thrown as a ninja star, going a farther distance faster while dodging enemies.
I hope this helps.
