You are waiting for the adventure puzzle Trail Light. Her character is a pretty pink block. He got into the maze, from where you can go to the next level, and there are a hundred of them. There is one condition in order to get to the checkered exit - it is to paint over all the cells with your color, in this case pink. To do this, you must lead the hero along the correct path that you had planned in advance. If you make the wrong turn, you have to start again. There is only one light path for the exit and you need to find it. Levels get complicated.
