It takes a lot of practice to land your board without biting the snow. However, once the game's control grows on you, it becomes second nature. You control your board with the analog stick and you hold down the Z trigger to crouch. Besides the A and B buttons to jump and crouch, the controls are simple. Again, it isn't the control that makes you crash, it's the learning curve.
Tricks are tough to pull off as well.
This is where the control IS a problem. If control weren't a problem, most people would be able to do 1080's almost every time. This is not the case. There are tons of holds and grabs that are easy to pull off, but the spins get more difficult after about 720 . Spinning while doing holds is also not an option.
