Hey, Thanks for playing!
So I've tried to explain the game-loop in the description. 
Basically, there is the Safe-Zone (in the middle of the island). The player may survive only by staying in the safe-zone when the storm hits.
Then when the player is in the safe zone, the storm can enter at every point under the white circle indicator.
So the game is designed in a way that the player must either stay higher than the White Storm indicator or inside it but covered from all angles. 
If you are still interested in giving it another shot, I've got a walk-through video on the game page:
