- it will be possible to fail a trick and crash head first into the snow?
Yes, I will tackle that shortly. I've been discussing with some friends how that will work from a technical standpoint.
- it will be possible to chain multiple tricks together to get even higher scores?
Not sure if you mean multiple tricks in one jump or holding a combo across multiple jumps but both will be possible.
The next demo is November 4th and should have both of these features. However, I don't think getting off the snowboard will ever be a feature.
