Watch out for a trap here, as well as for the wooden bridge that will collapse after you dash over it. Go right and use slides again to get over the larger chasms. You will find the first trap here and, to avoid death, perform a slide. Watch out after you reach the location shown in screenshot 1.

In the next area, smash all of the crates suspended from the ceiling, which you can easily reach by performing long bounces. In one of the next locations, jump carefully over the two green crates. You will run into even more trouble after you have obtained the red gem and unlocked the secret stage, where there are many more spots where you can die. Even on the main path ,you can encounter many traps and spots where you have to slide over ice. This one is a longer and occasionally burdensome stage. After you have done that, you can start Snow Biz, because it will be possible then to reach all of the crates on the first take. Therefore, it is better to consider playing the individual stages in a different order: start with Air Crash, take the secret portal there and complete the secret path in mission Snow Go, which will lead you to the location where you obtain a red gem.

You can obtain this stone by starting another stage in Ice Warp Room - Air Crash. Note - It has been mentioned above that you require a red gem, if you are going to smash all of the crates. To reach all of the locations with crates, you require the red gem from Snow Go.
