Sequel to Kurukuru Kururin. Once again you take control of Kururin as he pilots the Helirin, a helicopter whose long propellors turn slowly.
Each stage is a maze with narrow walls and other obstacles, and you must travel through each without letting the propellors touch anything. You can only hit three obstacles before the Helirin shatters, but you can restore health by flying over Heart Markers. Reach the goal and you will be assessed on how fast you completed the stage, but hitting obstacles adds time to your clock. You can find decorations for the Helirin, usually hidden in tricky areas.
There are 11 bonus stages that play differently to the main game, some starring Kururin on his own, the Helirin, or even Kururin's siblings.
In the first bonus game, Kururin has to fly through the sky while avoiding obstacles in order to reach the goal. It appears to have been based on Balloon Fight's Balloon Trip mode.
The backgrounds of some stages feature the GameCube.
