I have to admit I was a bit lost when first trying this. No matter what I did, my character would be killed by the little skeleton immediately in the first level. After trying it for several times (and got hold of the right timing), I started to feel the joy of this. Timing is the point that matters. It's a bit like a harder version of Temple Run but you need to attack the enemies along the way.
Generally speaking a unique runner game worth a try, though the graphics and design are pretty basic to be honest.
