The line between the robot and you turns red when you are close to the robot, and turns blue when you are far from the robot. If the line is blue, you can control the robot or if the line is red, it will move on its own. TYSM for playing!
sorry, i meant the sparks, i finished it without using them. When it was introduced they didn't do anything, so i stopped using
The sparks were meant for levels 3-6, because if you are unlucky it can get very frustrating. And level 6 is almost impossible without sparks or luck!
