EXTRA: Whiteout Achievement in Vampire Survivors

This achievement is cumulative and retroactive.

Orologions are the stopwatch powerups that, when collected, freeze all enemies and turn them blue. You will assuredly collect far beyond 20 by the time you complete the base game, but an easy way to grind them out is to replay Inlaid Library and go around breaking all the light sources, or play the second bonus stage and keep breaking light sources there.

Once you've collected a cumulative total of 20 of these across all runs, you'll unlock this achievement and the new level Whiteout.
