Gameplay
The player needs to blow a whistle to bring the many Tiny Warios on the screen together in a hexagonal formation to win the game. The whistle must be tapped five times. When the Tiny Warios come together, they transform into regular Wario. If this has not happened by the end, the game will be lost.
