People who have played Nintendo games would know that Nintendo games sometimes come packed with health advisories, urging players to rest their eyes after long periods of play. Although developed by Koei Tecmo, Fire Emblem Warriors also features such advisories.
As can be seen in the tweet by @ibbsters below, Fire Emblem Warriors features a cutesy verbal warning to the players to rest their eyes, especially after long periods of play or after late at night. The game also advises gamers to play in a well-lit room and sufficient distance from the screen. Just another way of Nintendo showing concern to your eyes
