Draw a single line to guide several balls to their goals in over 80 levels. Use gravity inverters or portals to reach outlying areas! Change the color of balls and change their behaviour.
Draw lines to reach
* Gravity Inverters
* Portals
* Colorizers
* Special Balls
* Black Holes
* and more!
Use lines so red, blue and yellow balls can reach their specific goals. First make a plan, then draw! Red balls can effect blue gravity inverters and thereby change the gravity of blue balls, making every level a challenge.
