In a new trailer running down accessibility features for Prince of Persia: The Lost Crown, Ubisoft has revealed a map option so smart that every Metroidvania should make use of it.
The Lost Crown lets you place "Memory Shards" on the map. Essentially, you take a screenshot of your current location and pin it to the map, and anytime you hover over that pin you can view the image you took. This gives you a quick, easy way to annotate the map with inaccessible locations you might want to return to when you unlock new powers.
