Most levels are easier to solve if you don't hang about: the longer you wait, the more uncertainty bites and the position becomes indefinite. Remember there's no friction so if you accelerate over half the screen you need to decelerate over the other half if you're going to stop before the other side. Level 2 can be solved by accelerating/decelerating to follow three straight lines (east-south-west) to the goal. Alternatively if you're feeling cocky you can accelerate east then throw in some south as you approach the corner: you'll bounce off the walls and break the wavefunction a bit but about 50% of the time the goal will trigger. If you haven't discovered already you can also skip levels from the menu ;)
