Artifact 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 playable 3D top-down survival-collection game titled "Artifact Run". Use a dark sci-fi arena viewed from a camera above and behind the player, with a perspective camera following the player at about 11 units distance. The scene should have a nearly black navy background and fog, a large flat dark blue-gray circular arena roughly 28 units in radius, a faint cyan ring marking its outer boundary, and a subtle square grid across the floor. Use cool cyan lighting with soft shadows and a clean futuristic neon visual style.

The player is a controllable humanoid/asset centered in the arena, scaled to about 1.7 units tall; if the supplied player asset cannot be loaded, use a glowing cyan capsule-like fallback character. The player begins near the south side of the arena at position approximately (0, 0.3, 8), faces the movement direction, and moves with WASD or arrow keys. Support Shift for sprinting, Space for dodging, and a touch joystick on mobile. Keep the game focused on movement and evasion rather than combat: there is no player weapon or attack system.

Place exactly 7 collectible artifacts around the arena in a fixed spread of positions. Each artifact is a small bright cyan/ice-blue glowing faceted icosahedron with a thin cyan torus halo around it. They float around y=.75, rotate continuously, and bob gently up and down. When the player comes within approximately 1.15 units, hide the artifact and increment the artifact counter. The goal is to collect all seven artifacts.

Add exactly 3 hunter drones/enemies. Represent each as a small bright hot-pink/red glowing spherical drone with a small white eye on its front. Start them toward the north and sides of the arena. Each hunter continuously homes toward the player's horizontal position, moves at a gradually increasing speed (base speeds approximately 1.4, 1.75, and 2.1, with a tiny time-based increase), turns to face the player, and ends the run if it gets within approximately 1.05 units. There should be no health bar or combat HUD; contact is simply a loss.

Build the interface as a dark translucent glass HUD over the 3D view. At the upper left show a rounded panel with the cyan uppercase title "ARTIFACT RUN" and a status line initially reading "Loading your asset…" and then either the loaded model filename followed by " · collect and survive" or the fallback status "Asset fallback loaded · collect and survive." At the upper right show a rounded panel with a large white number starting at 0 and the label "ARTIFACTS". At the bottom center show the hint: "WASD / arrows to move · Shift to sprint · Space to dodge · touch joystick on mobile".

On initial load, display a centered rounded translucent dialog over the arena titled "Artifact Run", with the text "Recover the glowing artifacts before the hunter drones catch you." and a cyan button labeled "Start run". Clicking it or pressing Enter starts/restarts a run, resets the score, player, artifacts, and hunters, and hides the dialog. During play, update the artifact count as collectibles are recovered. If all 7 are collected, stop the game and show a centered dialog titled "Arena cleared" with text like "All 7 artifacts recovered in [whole-number]s." and a "Play again" button. If a hunter catches the player, stop the game and show "Run ended" with text like "You recovered [count] artifact(s) and survived [whole-number]s." and a "Run again" button. Preserve the clean responsive full-screen layout, rounded borders, cyan accents, and dark navy sci-fi atmosphere on desktop and mobile.
