Mr. Shifter

You are Mr Shifter (the blue 'un) and you must send all four parcels off in the allotted time. Use the 'No Entry' sign to help steer the parcels where you want them to go. It's not so easy!! Extra points are gained for removing the ever increasing amount of 'Weighing machines' that appear from time to time and the quicker you are the bigger your bonus will be!
