Kuru Kuru Kururin is a puzzle game where you control the main character inside a helicopter as it navigates through a maze. Your goal is to find your brothers and join forces with them after finding them. To achieve this, you need to make precise movements, timing your turns carefully to avoid hitting walls, which will add 3 seconds to your time. Along the way, you'll also encounter power-ups that let you customize your helicopter's appearance.
The gameplay involves using the helicopter's propeller to move through the maze, while avoiding obstacles and trying to shave off precious seconds from your total time. With each completed level, you'll unlock new power-ups and upgrades for your helicopter, allowing you to tackle increasingly difficult challenges.
