There's no way to be definite without more details about the game. However, it could have a main character who is deeply affected by heliophobia. There might also be side characters such as friends or family members of the main character. These side characters could either support the main character in their struggle with the phobia or be a source of additional stress. Maybe there are also characters who are indifferent to the main character's heliophobia and just go about their normal lives in the game's world, which could create interesting interactions.
Well, without more information, it's hard to say precisely. But generally, if it's a game story related to heliophobia, it could be about a protagonist who suffers from this phobia. Maybe they are in a world where they are constantly forced to face the sun in some way, like in a survival game where they have to gather resources during the day despite their fear, and the story could be about their journey to overcome this fear or at least survive with it.
