Lost Colors

There were creatures who populated a strange world that made the world bright with smiles and joy. It was only later that good people fell asleep and the cities lost their colors, that the evil force stole the paint. It's your duty to wake the monsters up. It could be said that to build up the direction of the paint towards the monsters you should plant-machines from the bushes. It's necessary to make a chain of paint flows through crystals so that you can begin to paint the inhabitants of the next city.
