Azure Dash

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 2D endless runner titled “Azure Dash,” presented in a crisp orthographic Three.js scene using flat sprite/plane graphics. The camera should show a wide horizontal playfield with a dark navy/black space-like background, subtle scattered parallax white/gray square dots, and a dark navy ground filling the lower portion. Add a thin glowing cyan horizontal ground line across the screen. The player is a large blue cartoon hedgehog-like character sprite on the left side of the screen, facing right, auto-running while the world scrolls left. Use distinct player visual states: idle on the title screen, running during play, jumping in the air, and a game-over appearance. Keep the player fixed horizontally around x=-5.5 while objects move from right to left. Use a single-jump mechanic: Space, W, or ArrowUp makes the character jump only while grounded; use gravity so the character arcs upward and lands back on the cyan ground line. The character’s collision box should be smaller than its visible sprite, approximately 1.2 wide by 1.6 high.

Spawn solid red/pink rectangular crate hazards from the right at randomized intervals of roughly 0.75–1.3 seconds, with random width about 0.9–1.3 and height about 0.9–1.7; they sit on the ground and scroll left at the current run speed. If the player’s hitbox overlaps a crate, immediately end the run, play a low hit tone, switch to the game-over sprite, save/update the best score, and show a centered game-over panel with Score, Best, and “Press R to restart.” Spawn bright yellow collectible bolt/square items from the right at randomized intervals of roughly 0.55–1.25 seconds, at varied heights above the ground (about 1.3–3.7 world units); they rotate while moving left. When the player overlaps a collectible, remove it, play a short high collect beep, and add 75 points.

The run starts at score 0 and speed multiplier 1.0x. Score continuously increases over time at roughly 22 points per second multiplied by the speed multiplier. Increase difficulty continuously with speed multiplier = 1 + score/600, so the displayed speed rises as the score increases and the world scrolls faster. Remove objects once they leave the left side of the camera. Before starting, show a centered translucent black rounded panel with a thin subtle border and exactly the instructional hierarchy: large uppercase “AZURE DASH”; “Jump with Space — avoid crates — grab bolts”; “Press Space to start”; and a smaller tip “Tip: You can also use W / ↑. Press R to restart.” Pressing Space/W/ArrowUp should both start the game and jump if starting from the title screen. R should reset the run and hide the message. Also allow mouse click or any key to initialize browser audio, consistent with autoplay restrictions.

Add a fixed HUD at the upper-left with three dark translucent rounded pills bordered subtly: “Score: 0”, “Best: 0” (persist the best score in localStorage under an Azure Dash best-score key), and “Speed: 1.0x”. Use a clean bold system sans-serif font with pale blue-white text. Use Tone.js or equivalent synthesized audio: a short triangle-wave C5 beep on jump, a short high E6 beep on collection, and a lower G2 tone on collision. Keep the visual style minimalist neon arcade: flat colors, no detailed scenery, crisp pixel/nearest-filtered sprite textures, translucent HUD, and responsive full-window layout.
