The world of blue and red men will open you the game Crowd Gate. A conflict arose between them, in which only one side should have been going on. You will help blue and for this you need to pick up the maximum crowd, since you can only win the number. To increase the crowd, go through the blue gates, go around red barriers in any form. But it will not be possible to get around the red crowd, you will have to fight with it and if your little men are more, the losses will be minimal. At the finish, your crowd will be built into the tower to distribute on the finish staircase and get a reward in crystals. They can be spent on buying improvements before the next level in Crowd Gate.
