Game title: PROJECT HORIZON, as an in-game screenshot in a hand-drawn ink and watercolour style. Palette: paper #f2e8cf, ink #283618, player tomato #bc4749, threat plum #6d597a, accent leaf #a7c957. 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.
