Rail Rush Range

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 3D browser game titled "Rail Rush Range" using a dark neon sci-fi roller-coaster shooting-range presentation. Use a tall, portrait-friendly full-screen view with a deep navy background and fog, a large flat dark-blue ground/track area, scattered tiny cyan stars in the sky, soft cyan lighting, shadows, and glowing accents.

The player rides a compact purple rail cart through a straight track. Build the cart from simple geometric parts: a wide purple rectangular body, a dark seat on top, and a short gold/orange barrel projecting forward. Place two parallel dark blue rails beneath/along the cart, extending straight into the distance, with glowing cyan semicircular arch gates crossing the route at intervals. Include a distant coaster/rail bend prop off to the left as a visual set piece if available, but it is decorative rather than interactive.

The core mechanic is an on-rails target shooting ride. When the ride starts, move the cart steadily forward along the negative-Z track for about 12 progress units, bobbing very slightly up and down as it travels and subtly pitching with the motion. Keep the camera in a forward-facing third-person/ride view near the cart, with aiming able to shift the camera/look direction slightly horizontally and vertically. Spawn nine red/pink glowing torus-shaped targets ahead along the track, distributed at increasing distances (roughly every 7 world units starting around z=-16), with varied lateral positions up to about 5 units from center and vertical positions around 1.7, some higher or lower. Each ring should face generally toward the player and gently drift side-to-side/up-and-down while rotating. The player aims a central glowing circular crosshair and shoots targets with a ray cast from the camera through the aim point. A successful hit turns the target gold/orange, enlarges it briefly, awards points (100 for the first and increasing by 15 for each later target) multiplied by the current combo, then removes it after a short delay. Missing a shot resets the combo to 1. Start at combo 1; successful hits increase combo up to 8. There is a short firing cooldown of about 0.18 seconds and a brief bright flash effect after firing. The ride ends automatically after the forward run, showing the final score and a replay option; the completion message can praise a high score above 2500 as a "Bullseye legend."

Controls must work on desktop and touch. On desktop, move the mouse to aim, click or press Space to fire, and press Enter to start. On touch, drag on the game view to aim and tap the large FIRE button to shoot. Provide a START RIDE button on the ready overlay and change it to RIDE AGAIN after completion. The ready overlay says "Ride Ready" and "Hit the glowing targets before the track drops." while the ride is not active.

Use a minimal HUD over the 3D scene: at top left, a translucent near-black rounded panel with cyan outline reading "RAIL RUSH RANGE" and "Combo x1" (updated as appropriate); at top right, a matching panel reading "SCORE 0" and "SPEED 1.0x". Increase displayed speed gradually from 1.0x based on progress, reaching approximately 1.5x by the end. Put a bright cyan glowing ring crosshair with horizontal and vertical cross lines at screen center. At the bottom center show "Drag to aim • Tap FIRE to shoot" and on wider desktop layouts append "• Mouse to aim • Click / Space to fire". On touch layouts show a large circular orange FIRE button with a yellow border and orange glow in the lower-right corner. Keep the visual style clean, sparse, high-contrast, futuristic arcade UI: white bold text, cyan outlines/glows, orange firing control, red target rings, purple cart, and dark blue environment.
