In recent updates you can now buy a Helmet or a Chasm rescue pick axe that will save you from a crash and from a chasm. You should buy these when you have spare coins so that you can keep going if you need to hit several backflip goals, a length goal and other tricky challenges. You'll find them in the store. You can also buy a Llama horn that will show up as you snowboard through the map. When you hit it, you will see a stampede of llamas coming at you and this can help with a llama based goal.
