Crash: Wrath of Cortex - Eskimo Roll (Platinum)
As early as the first slope, you want to be careful and gain a lot of speed without missing the time trial starting clock entirely, all while then manuevering to hit the time crates and fitting into the bridge to not lose speed and then moving properly on odd terrain afterwards. Make sure to dodge the blocking enemy at all costs, as it can really slow you down, and be careful with the penguins in the stage as well for the same reason.
With the next downward slope, you want to make adjustments to your movement early so you can stay in control and reach the time crates without letting the terrain mess with that too much. Make sure to not miss the time crates by the fence and, once you reach the next downward slope, go mad and roll down, slowing down for the time crate on the cliff and adjusting direction to get the next time crate on the ground without falling into the holes or bouncing off into the nitro crate corner.
Make sure to keep in mind that going too fast will allow the flamethrower enemies to damage you easily, and be wary of the penguin before the cycle platform in particular as it can bounce you backwards like nothing - another flamethrower enemy comes right after, so be on your guard there too. The next slope area can heavily mess with your movement, but you can take advantage of that to reach the last time crate before the cycle platforms with no issue. For the cycle platform bit, you'll want a decently favorable cycle - if they happen to have a bad one, restart.
While the time crates afterwards are alluring, it's best to take the ones on the middle path to not fall off, and carefully bounce between holes using the slope terrain to reach the final time crate in the way, rolling downwards and making sure to remember where the teleporter is to not miss it.
