Try to survive and defeat the boss (spawns after 45 seconds). C to change planes (makes no difference-just looks and sounds change). -After you defeat the boss, the game continues. -Multiple power up planes will spawn at once if your game is lagging. -The clouds only appear when the boss is hidden (it interferes with the health bar).
