This game is meant to promote SODIS (Solar Water Disinfection) method that can solve many problems in the Third World. To disinfect water using SODIS method, the water must be placed in a plastic (PET) bottle and left under direct sunlight for some time. In this game the citizens of a little village put their water in PET bottles and leave them on the sun. They do it by themselves and you don't need to take care of this. All you need to worry about is providing enough sunlight. There will be clouds that may threaten the whole process. Your goal is to move these clouds so they will not cover the sun. To do so, click on them and drag them away from the bottles.
