A run of Crash 4's Seeing Double getting the N.Sanely Perfect relic (break all crates without dying once, just like gems were in Crash 1 PS1 original version). I also receive no damage in the whole run. Seeing Double is the last level in the game, and during the first half of the level, you use good 'ol Cortex, which, as always, is quite fun to play. The second half is the same mask gauntlet from Cortex Castle, with minor modifications. In fact, I think that Seeing Double has the "alternate timeline" recycled segment with the least changes compared to the original segment, which is a bit disappointing. I think that this should have been a 100% Cortex 5-6 minutes long level, without the Crash/Coco segment, to be honest.
