Not really feeling this game so far, mainly because of the "deadly descents" aspect of it. In these portions of the game when you mess up it either forces you to use rewind, or start over at the very top.
So basically you're stuck in 1980s videogame design where you have to try and try again until you pass the level. This is very much against the tone and feel of what made previous SSX games so good, as it leaves you feeling constrained rather than free.
