The purpose of this puzzle game is to run one box into the exit. Seems simple enough right? Well throw in the fact that missing the sensors will fling you into space, and bombs are always blowing things up and you've got yourself a puzzle which you better make sure you beat fast, because take to long and you may need to start over.
A good plan is to make sure you have at least a couple steps laid out before you start the level (both in the beginning and the end).
