The generic “jumping puzzle rules” apply (when on slanted platforms, try to jump from the highest side of one platform to the lowest of the other, turn with the mouse, don’t release the run key unless you really have to, remember you can make curved jumps, etc.). The only things specific to this puzzle are:
Be lucky and get an instance without too many full-size norns. Apparently Arena Net didn’t read the feedback from the Halloween puzzle… (how hard could it be to render other players as small snowmen, for example?).
Go to your options screen and move the camera position all the way to the right. Just as moving it to the left helped prevent the camera from getting stuck in the Clock Tower, here it’s to the right. If you leave it in any other position, your camera will probably start bouncing when you’re near a tower. Even all the way to the right it still bounces (especially with asura characters), but less.
You can do full-length jumps onto the candy sticks as long as you jump diagonally. If you prefer to jump perpendicularly, you’ll have to release the run key mid-jump. If you can do the beam jumps in Fawcett’s Bounty, you can do these easily. The main problem with these jumps is the camera getting stuck in the tower (see above).
Presents shake before exploding, so don’t jump towards one that is shaking, and if it starts shaking while you’re in the air, jump to another one as soon as you land. The ones near the edges are less likely to pop than the ones in the middle.
Dodge when you run in front of the snowman (after the exploding presents). Sometimes he knocks you off even though the “wind” effect doesn’t seem to render. Dodging should make you immune to it.
In the snowball section, when avoiding the second snowball (the part with two small platforms on your right), avoid jumping “up path” from the smaller of the two platforms (jump perpendicularly to the snowball path). There’s some bug with the hitboxes here and sometimes you hit an invisible wall.
Don’t get too close to the second snowman. You just need to avoid the snowball.
Follow the blue presents and the candy canes to reach the end. The platforms are pretty generous in that section.
Everything else is pretty straightforward and anyone who can do the regular (non-timed) jumping puzzles without stopping for a coffee on every platform should be able to finish this one without being bothered by the timer.
Other than the strange bug that sometimes teleports me back to the lobby for no reason (see other thread), by far the biggest problems I had were the camera position (I normally have it all the way to the left), the non-rendering snowman wind, and the invisible wall in the snowball section.
