Komorebi is a game in which the player character's health bar is replaced with a "light bar." When the light bar reaches 0, the player receives a Game Over - much like a traditional health bar. Unlike a health bar, however, the light bar fills under a light source and depletes when the character is in shadow. Based on this concept, players are placed in levels where light and shadow vary. For example: a forest where light filters through foliage, a cave where torchlight refracts off crystals, or a midnight highway lined with lamp posts.
