The Animation Play

code of animation play
After press the play button, the key code 's' was built to control the mountain
falling down to the sea. In contrast, press 'w' to make it rise above sea level.

I covered a lot of small stones on the iceberg to simulate the collapse of the iceberg melting process, the animation began to play, the mountain began to fall before the stone will begin to fall, and the speed of each stone fall are different that this would make it look more realistic melting iceberg.
