You have to reach your destination in each of the level while avoiding obstacles & pitfalls.
BUT the fun part is that you are BLIND in this game so you cannot see any platforms or pitfalls or obstacles.
What?? Finding strange? getting confused?
You have some magical balls & bullets in every levels.
Throw balls or fire bullets to get imaginary position of platforms / pitfalls / obstacles.
Use that wisely to find your way out.
