Forgot to mention here, but we launched version 0.4.3 this week, which most notably includes a whole bunch of multiplayer performance / networking improvements. More info here:

Also, @McLS - thanks for the feedback! The pine forest is still WIP so we do have a bunch more wooden features to add to it to make it even cooler. I'll keep in mind the bumps to give you little pops for 3s and 5s.
Rails still need some work, both on tweaking the code but also just new animations and polish on the visuals of hitting the rail. This will come in the future once we do a new batch of animations (probably early 2015)
Butting can be improved with new animations. I think we can probabl bend the skis, but maybe not... would be just in the animation which shouldn't be too hard.
2015 will be a fun year!
