Star Scoot

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 Three.js-style 3D top-down neon survival game titled “Star Scoot.” Show a large circular dark navy sci-fi arena, viewed by a pulled-back perspective follow camera from above and behind the player. The arena floor is a glowing deep-blue circular platform with a cyan torus rim and a faint cyan grid; the background is nearly black-blue with fog and scattered small white/cyan star specks. Use clean emissive low-poly geometry, soft shadows, and glassmorphism UI panels.

The player is a tiny hovering cyan comet/crystal: an angular glowing turquoise icosahedron with a bright white spherical core, a dark circular shadow beneath it, and a translucent gold/yellow spherical shield bubble whenever shield charges or temporary invulnerability are present. It moves freely across the circular arena but cannot leave the boundary. Movement accelerates and has inertia/friction, with WASD or arrow keys on desktop and a large left virtual thumb joystick on mobile. Press Space on desktop or a large right-side “DASH / Space” touch button on mobile to dash in the current movement direction (or forward if stationary). Dash has about a 1.05-second cooldown and briefly makes the comet faster and able to punch through enemies.

The goal is endless survival and score accumulation. Blue/cyan faceted star pickups float and bob around the arena; collect them for 10 points multiplied by the current combo. Gold faceted star pickups are rarer; collect them for 25 points multiplied by combo and restore one shield charge. Collection raises the combo up to x9 and refreshes a few-second combo timer; if the timer expires, reset combo to x1. Keep replenishing pickups as they are collected and over time, maintaining roughly 9 initial pickups (mostly blue, with two gold) and up to around 10 during normal play. Add brief colored expanding ring pulses and small spark bursts on collection.

Red/pink hovering drones spawn around the outer rim and home toward the player with a slight side-to-side wobble. They are rounded low-poly red enemies with a small spike on top. A normal collision costs one shield charge and briefly grants invulnerability; if no shield remains, end the run. If the player is actively dashing through a drone, destroy it, award 18 points multiplied by combo, and show sparks/pulse effects instead of taking damage. Enemy spawn rate and speed gradually ramp with wave/time, but cap ordinary enemy count around 12 (and around 4 during a boss encounter). Award a small amount of score continuously for survival, approximately 2 + combo*0.35 per second.

Time alive defines the wave: wave = floor(seconds alive)+1, starting at wave 1. A giant boss begins at wave 100 and remains until defeated or wave 125. The boss is a floating purple glowing faceted crystal/icosahedron with a bright white core, a pink emissive halo ring, and six outward spikes. It homes toward the player with a gentle wobble. The boss has 8 HP at wave 100, receives damage only when the player dashes into it, and each dash hit removes 1 HP, awards 36 points multiplied by combo, and produces bright pulse/spark feedback. Destroying it gives a large reward (240 multiplied by combo) and 2 shield charges; if wave 125 arrives first it automatically shatters for a smaller reward (120 multiplied by combo) and 1 shield. On boss contact without dashing, apply the normal shield/hit behavior. Start subsequent boss cycles every 100 waves with scaled HP. Keep the boss inside the arena boundary and show its HP in the HUD.

At initial load, display a centered dark translucent rounded modal titled “Star Scoot,” with the description that the player is a tiny comet surfer in a huge neon field, should grab stars, build a streak, and survive to boss waves. Include desktop controls “Move: WASD / Arrow Keys; Dash: Space,” mobile controls “left thumb joystick; right button,” a bright cyan “Start Run” button, and a secondary “Restart”/“Reset Run” button. Starting a run hides the modal; keyboard movement, joystick use, or dash can also start it. On death, show a centered “Run Over” modal with score, wave, and saved best score, plus a “Run It Back” button and reset option. Persist the best score in local storage.

Place a glassy HUD across the top with large rounded stat cards for SCORE, survival TIME/ALIVE, WAVE, STREAK or COMBO, and SHIELD; initial values should visibly communicate score 0, alive/time 0, wave 1, streak x1, and shield 2. Include a compact instructional panel reading that the player should scoop stars, dodge red drones, and use dash to punch through danger, with gold stars recharging shield, plus a visible “Next boss at wave 100” message. During a boss, replace that with boss wave, current HP/max HP, and the wave at which it shatters. Use responsive touch controls at the lower corners: a translucent circular joystick with glowing cyan thumb at lower left and a circular DASH button at lower right. Add brief toast messages such as “Go!”, “Dash!”, “Shield blocked a hit,” “Gold star: shield +1,” and boss notifications.

Animate the comet rotation/core pulse, floating and spinning pickups, drone/boss hovering and rotation, cyan arena rim/grid shimmer, expanding impact rings, and short-lived spark particles. Keep the visual style minimal, polished, futuristic, colorful, and phone-friendly, with no invented weapons, shooting, lives, or alternate levels beyond the described shield, dash, pickups, drones, endless waves, and boss encounters.
