Gravity reverse matrix
This resource will be available from the third region in the story.
It activates the jumping special ability. When you will collect the first one, a green image will appear on the lower right corner of the screen, with a number above it. Taping the screen on that area will give an impulse to the ball and will cause it to jump up.
From that moment, there will be a fixed amount of time until you land back. While in the air, you can move sideways, break, accelerate or use any other ability except jumping.
Usage and behavior of a gravity reverse matrix can be seen here (youtube video).
