N. Verted Mode

N. Verted Mode is a mode introduced in Crash Bandicoot 4: It's About Time. In this mode, every level is flipped around so that what should be on the left is now on the right, and vice versa. Each level also has a different filter depending on which dimension the level belongs to. For example, the levels in Salty Wharf are completely white but your actions will bring back the colour. On top of that, the level's soundtrack is slightly different and the clear gems have been replaced with "N. Verted Gems", which are upside-down. The hidden gem is also moved to a different location.

Just like the clear gems, the "N. Verted Gems" also count for 106%.

N. Verted Mode also introduces a new type of collectible: the Bumpa Berry, which behaves similarly to the Wumpa Fruit.
