This jump can be so infuriating that it may cost you $350 in broken computer parts.
The first tip is to stay facing left after the first walljump (towards the walljump itself).
Turn to face the other direction as you hop off the second wood platform. Keep facing right and making
a nice hard arc all the way through the sloped platform jump until you land on the first curvy icy part.
On the second walljump, it's best to keep facing right (towards the walljump itself) for a split second
after walljumping.
If you turn to face left immediately after the second walljump, your line won't be quite as good.
The delay should be less than half a second.
