Control your drone and rescue those stranded at the scene of a fire!

Swipe to move the drone, hold to raise it, and release to lower it.

When the ball hanging from the drone touches a bucket of water, you can lift the bucket.
When the bucket touches the flame, water from the bucket is dropped into the flame to extinguish it.

The longer it takes to extinguish the flames, the more powerful the flames will become, and the less likely you are to be able to save your rescuer.
Also, depending on the strength of the flame, it may not be possible to extinguish the fire just by dropping the water in the bucket once, so if the flame is not extinguished, it is necessary to drop the water until it is extinguished.
