Visually, the game is a product of its time, featuring hand-drawn 2D sprites and backgrounds that prioritize a soft, pastel aesthetic. The "sunlight" in the title is reflected in the art direction, which utilizes bright lighting effects to create a nostalgic, summer atmosphere.
The "sunlight" here acts as a metaphor for truth serum. You cannot hide in the shadows of the golden hour or the blue light of a screen. The high-noon sun forces a confrontation with imperfection.
Forget the rule of thirds. Forget golden hour. Go outside between 11:30 AM and 1:00 PM. The sky should be clear, or at least bright. The sun should be directly overhead or slightly behind you.
As the movement grew, it attracted critics. Some argued that romanticizes decay and squalor. Western media critics labeled it "Japanese Wabi-Sabi meets doomerism."
