FIND THE TRUTH., full body, plain background. Drawn as a rough storyboard sketch: grey pencil and marker on white paper, one accent colour, loose flat shapes, no shading detail, no background clutter. Everything is original: never draw or resemble characters, places or logos from existing games, films or brands (no red-capped plumbers, no famous mascots), even when the idea names one. Keep the pictures honest: they promise what a small first version of this game, made in a game engine in a few days, can look like. Simple readable shapes, clear silhouettes, few flat materials, the in-game camera view. Never film stills, photoreal renders, AAA key art, detailed textures, cinematic lighting, or anything that looks like a big-studio game. No text, UI, HUD, logos or editor screens inside any image.
