My god... A USE for the Quick Slide! And if only you had used the Christmas/winter mod...
...I demand Crisis City be done now.
Also, I'm surprised the game doesn't, for lack of a better phrase, shit itself when you go through a rainbow ring/up a rainbow ramp with the board, considering you can't do tricks.
I'm more surprised that the game doesn't shit itself when I do anything you don't usually do with the snowboard, the trick animations are literally the only thing that will crash the game, you can even do Wall Jumps!
Also every level with even a hint of platforming or open level design will be a pain to do with the snowboard because you are forced to move forward, 2D sections are even more painful because you can't turn around while in the snowboard in 2D mode.
