Neon Rampage: Pinball Runner

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 “Neon Rampage: Pinball Runner,” set on an orbital/void highway with a dark futuristic neon aesthetic. Use a third-person perspective camera following a chrome metallic sphere rolling downhill along a wide straight roadway. The road should be made from repeating segments, about 10 units wide, with dark navy road surfaces, glowing purple/magenta edge rails, occasional bright green speed strips, deep black-purple background, fog, bloom-like emissive lighting, cyan and pink point lights, and a starless void atmosphere. Keep the player sphere centered near the foreground while the highway and objects move toward the camera to simulate forward travel. The sphere is silver/chrome with high metalness, a subtle blue emissive tint, and a glowing magenta ring around it; it visibly rolls as it travels. Smoothly follow the player’s horizontal position with the camera, looking down the highway toward the distance.

The core loop is an endless survival run. On start, hide the overlay and automatically move the sphere forward at about 17 speed units, increasing speed through interactions, while continuously increasing distance and score. Generate and recycle repeating highway segments, obstacles, and coins ahead so the run can continue indefinitely. Constrain steering to roughly the road width: keyboard A/D or left/right arrows move the sphere left and right, and mobile pointer/touch dragging on the left or right side steers it. If the sphere leaves the allowed roadway, end the run. The player can perform a brief heavy slam with Space on desktop or a single tap on mobile; this briefly increases speed, creates a cyan burst of particles, and lets the sphere smash crystal barriers. A double tap on mobile or either Shift key activates a magnetic shield for 2 seconds, with a yellow burst on activation. The shield attracts nearby coins and pulls nearby mines toward the player, as suggested by the magnetic-shield HUD behavior.

Populate the highway with these actual obstacle types, distributed randomly across the lane width and recycled from behind to ahead: red glowing faceted explosive mines; translucent cyan glowing crystal/glass towers of varying height; bright pink rotating pinball bumpers; and occasional futuristic ramp pieces. Collision happens when an object reaches the sphere’s forward collision zone and is close horizontally. A mine detonates and immediately ends the run unless the magnetic shield is active; a shielded mine is destroyed and awards score and multiplier. A crystal tower is successfully smashed only while slamming or while traveling above the high-speed threshold, awarding points and multiplier; otherwise it costs points and resets the multiplier. Hitting a pink bumper awards points, increases speed, and makes the sphere bounce upward briefly. Hitting a ramp awards points, increases speed, and lifts the sphere briefly. Add rotating gold ring-shaped coins along the road; collecting one awards points scaled by the current multiplier and slightly increases the multiplier. Use bright particle bursts for slam, coin collection, shield activation, successful obstacle impacts, and failed crystal impacts.

Implement scoring and progression faithfully: score increases continuously based on speed and multiplier, distance increases with travel speed, and the multiplier starts at 1x and can increase up to 10x from coins and successful interactions. Display whole-number score and distance in meters. Speed should visibly affect a “RUN ENERGY” bar and be shown in km/h using the game’s speed conversion; show a “MAGNETIC SHIELD” bar that drains over its 2-second duration and reads READY or ACTIVE. The run should become faster through slam, bumper, ramp, and other successful actions, with a maximum speed cap around 40. At very long distance, cap the multiplier at 10x.

Build a fixed HTML/CSS HUD over the canvas. At the top left show glowing magenta “NEON RAMPAGE” branding and the cyan subtitle “PINBALL RUNNER // ORBITAL HIGHWAY.” At the top right show a dark translucent rounded stats panel with SCORE, DIST, and MULTI values. At the bottom left show the rounded dark meter panel with the magnetic shield label/value and cyan-to-violet shield bar, then run energy with a yellow-to-pink progress bar. At the bottom right show the instructions: “A/D or arrows: steer · Space/tap: heavy slam” and “Shift/double tap: magnetic shield.” Use a nearly black purple background, pale blue-white text, neon pink headings, thin purple borders, rounded panels, and glowing shadows.

Before the run begins, show a full-screen semi-transparent dark overlay and a centered rounded card with a purple/pink border and subtle glow. The card title is “Neon Rampage,” with the exact instructional message: “Roll the chrome sphere downhill, smash through crystal barriers, hit bumpers, collect coins, and survive the void highway as long as possible.” Include a bright pill-shaped pink button labeled “Drop into orbit,” plus the small mobile hint “Mobile: drag left/right to steer · tap for slam · double-tap for shield.” Clicking the button starts or resets the run. When the run ends, reuse the overlay card, change the title to “MINE DETONATED” if an unshielded mine caused the loss, otherwise “RUN ENDED,” and show a message reporting the reached distance and score; change the button to “Run again.” Also support Enter to restart after game over. The final result should feel like a polished neon pinball-inspired downhill endless runner, with the chrome ball, hazards, bumpers, collectible rings, escalating speed, score/multiplier feedback, and responsive desktop/mobile controls all visible and playable.
