Antiban Walkthrough Sokoban Cool Math Games

In Antiban unlike the usual Sokoban, the main character does not push the blocks, but pulls the blocks along. In each level there is a transition door, usually it is closed by other doors. To open this door you need to press all the buttons that are on the level. In some levels there are several heroes who move either in one direction or in opposite. The game is taken from the site Cool Math Games.
