Change and make bigger several geometrical objects and use them to reach the line. The principle is really easy that a child can play. But the difficulty…. oh the difficulty.
Every level always contains two things. Line marks where you have to get an object and minimally one geometrical face. When you click at one of them, you can make it grow and bigger. Use this skill to move some other stuff and faces. You can make the burst as well. The game is good but the difficulty made me to use walkthrough quite often.
