Generated from: a scene from a small video game about: Create a 3D mobile endless-runner game from scratch. The player automatically runs forward through an endless environment made from procedurally generated track segments. CORE MOVEMENT: - Third-person camera behind the player - Automatic forward movement - Three lanes: left, center, right - Swipe left/right changes lanes smoothly - Swipe up makes the character jump - Swipe down makes the character slide - Smooth acceleration and responsive movement - Gravity and believable jumping physics ENDLESS WORLD: - Generate track sections continuously - Recycle sections behind the player for performance - Generate different track layouts and obstacle patterns - Always make sure at least one playable route exists - Gradually increase game speed and difficulty GAMEPLAY: - Collectible items along the track - Distance-based score - Increasing score multiplier - Obstacles requiring lane changes, jumping, or sliding - Collision causes the run to end - Game-over screen with score, distance and restart button MOBILE: - Designed for Android phones - Large, responsive touch controls - UI must scale correctly across different screen sizes - Optimize the 3D graphics for mid-range Android hardware VISUALS: - Modern high-quality 3D graphics - Dynamic lighting - Attractive environment - Smooth character animation - Particle effects for important actions - Strong sense of speed - Professional-looking HUD and menus IMPORTANT: Do not copy Subway Surfers assets, characters, logos, maps, music or artwork. Create completely original assets and visual identity. Build the first playable prototype first. Do not add shops, multiplayer, complicated progression or unnecessary features yet. Make sure the basic running, lane changing, jumping, sliding, obstacle collision, procedural track generation and scoring work correctly before adding anything else., as an in-game screenshot in flat colour 2D shapes with a bright limited palette. Palette: sky blue #8ecae6, grass #3a7d44, player sunflower #ffb703, threat red #d62828, accent white #fdfcdc. 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.
