World of confusion

Oh what a nice game today, you are going to save people by drawing lines. The people hold a coins and they are absolutely defenceless. This time you use a pencil and with it you draw bridges and obstacles to save them all and get them where they need. The painting is really fun, for example to get them over a water and fire you just draw a nice bridge and they are saved. But you have to remember that no line lasts forever and after some time it disappears. For every level you have given number how many people must be saved. The score is the coins you get from the survivers.
