Guardian Run

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Create a browser-playable 3D endless runner titled "Guardian Run". Use a third-person perspective camera positioned behind and slightly above the player, looking forward down a long forest lane. The scene should use a dark magical woodland palette: deep green background and fog, a broad green ground plane extending into the distance, soft pale-green lane guide stripes at x positions -2, 0, and 2, and warm directional sunlight with soft shadows. Place bush props along both sides of the lane as passing scenery.

The player is a small textured forest guardian character, loaded from the supplied uploaded OBJ/MTL/PNG asset, normalized to about 1.65 units tall and centered in a player root. The guardian begins in the center of three lanes and continuously runs forward while the world moves toward the camera; the player itself remains near z=0. Smoothly interpolate horizontal movement between lane positions -2, 0, and 2, and give the model a subtle running/bobbing animation and slight turn toward the target lane.

Core gameplay is an endless arcade run. On starting, reset the score and player state, then continuously increase forward speed gradually from about 13. Spawn obstacles far ahead around z=-43 at random intervals: either a Kenney-style log or cliff rock, randomly placed in one of the three lanes. Logs and rocks travel toward the player as the course advances. The player must switch lanes with Left/Right arrows or A/D (also provide on-screen left and right touch buttons), and jump with Space, W, Up Arrow, or an on-screen JUMP button. Jumping applies upward velocity, gravity brings the guardian back down, and a jump can only begin while grounded. An obstacle collision occurs when the player is in its lane and close to it, unless the guardian is high enough in the air; collision ends the run immediately.

Also spawn collectible glowing green seeds in random lanes ahead, floating around y=1.25 with gentle bobbing and rotation. When the guardian reaches a seed, collect it and increment the score. Seeds should be bright lime, faceted/icosahedral, emissive, and have a small green glow/light. Spawn side bushes frequently and move them toward the camera; remove distant objects after they pass the camera so the run remains endless. Give the player a brief initial invulnerability window after starting, approximately 1.1 seconds.

Build an HTML overlay HUD over the 3D canvas. At the top left show a dark translucent rounded panel reading "Seeds 0 · Best 0" with the live seed count and locally persisted best score. At the top right show a matching hint panel: "←/→ or A/D change lanes · Space/W/↑ jump". Before play, show a centered translucent panel with the large title "Guardian Run", the subtitle "Dash through the forest, dodge logs and rocks, and gather glowing seeds.", and a green rounded "Start Run" button. When a run ends, replace the title with "Run Over", show text explaining how many glowing seeds were gathered and to dodge earlier/chase a new best, and change the button to "Run Again". Persist the best score in local storage. Include bottom touch controls: paired left and right arrow buttons at bottom left and a large JUMP button at bottom right, suitable for mobile. Press P to toggle pause during a run. Keep the visual style polished and safe/arcade-like, with high-quality textured model and asset-library forest props, fog, lighting, shadows, and responsive full-screen layout.
