Bonus tasks attempted. (These are open to interpretation but I think my game has met them.)
3. A place that fills with light
Start at least one location mostly dark. By the end of the game, that same place should be clearly brighter because of what the player did. Aim for several distinct lit spots that only appear after player actions.
4. A story about the light
Give the light some meaning in the world of your game. A line of dialogue, a note, a memory, a short text on screen. Extra love if you sneak in a Hebrew word like or for light, ner for candle, or neshamah for soul.
5. Someone changed by the light
Show at least one character, creature, or community that clearly changes because the light spreads. Maybe they wake up, calm down, open a gate, sing, remember something, or choose a different path.
