Those levels look insane. I hope it starts off easier than that.
Yes, there's 12 easy levels that introduce you to the various game elements, and then 6 medium difficulty levels. After that is the hard levels.
In addition there's 3 seperate skill levels with varying effects. On easy, you get more time/arrows in each level, less obstacles, less crystals to collect, and the runners move slower.
Why are you still using Flash Player 9?
That is the standalone player. I find it actually runs faster than the Flash 11 standalone player.
