Back, well this is pretty cool, at first when I saw the controls I thought it was going to be a nightmare but it wasn't

there's you trick buttons on the left side of the screen (only the tricks you've unlocked appear) and on the right side you have a crouch button and a dial you can spin for horizontal spining, you tilt your device for back/front flips, now this all sounded confusing but you get the hang of it really quick and it makes for a really good game where you have really good control over what you do, there's the usual kind of the star raiting for the levels,
For high score, all snowflakes collected and not crashing.
The levels themselves have objectives to complete too which make you do certain grab tricks or grinds etc.
overall this is looking very cool and well worth checking out.
The only thing I'd like to see altered would be to have the spining dial above or below the jump button not inline with it as it makes you reach into the screen.
I'd love some kind of endless mode where you can just cruise down a randomly generated mountain pulling off cool tricks, maybe until you crash or something? Just an idea.
This was a nice surprise release of the week for me,
