Your task is to help the cleaners clean the windows by holding their rope on the roof top. As you hold the rope, you will feel the pressure and after some time you will have to swap with other workers who are free so that you can take rest.

And like wise after taking some rest you will have to help other helpers who are exhausted and take their place so that the tired helper can take rest.

As the level progresses you can unlock chair and a fan to take rest and upgrade the helpers strength and speed

So keep helping and clean all the building glass windows
