Level 1 is the first level of Rolling Sky and is the easiest and shortest of all the levels. It is the first and only level to use the Massiftheme. Like all other levels in the initial release, this level uses basic obstacles. When you score 70% or higher on the level, you unlock the bonus level: Illusion.
This is one of the three levels featured in the trailer, the others being Level 3 and Level 4 and Level 5
