Cube Rush

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 arcade game titled "Cube Rush". Use a fixed elevated top-down camera looking down at a square 22x22 dark blue arena, with a perspective view that shows the floor and shadows. The arena floor should be deep navy/teal with a subtle square grid, surrounded by low glowing teal perimeter rails on all four sides. Add five chunky dark blue rectangular block obstacles arranged approximately at (-5,-3), (4,-4), (-3,5), (5,4), and (0,0), each about 1.6 wide/deep and 1.1 high, with slight rotation on alternating blocks and soft shadows. The scene should have a dark navy background and fog, cool cyan hemisphere/directional lighting, and a polished neon sci-fi aesthetic.

The player is a small glowing cyan object near the south side of the arena (starting around world position x=0,z=8): an upright faceted cylinder/cone-like core about 0.7 high with bright cyan emissive material, plus a thin luminous ring lying flat around its base. It should cast a shadow and rotate its core while moving. Control movement with WASD and arrow keys, and provide an on-screen virtual stick/touch movement control on mobile. Movement is free in the horizontal arena plane at roughly 7.2 units per second from an elevated top-down view.

The core objective is a frantic timed collection run. When a round starts, reset the score to 0, combo to x1, collected count to 0, player to its starting position, timer to 60 seconds, and place 8 glowing collectible cubes in random valid spots across the arena. Valid cube locations are inside roughly x/z -9.3 to 9.3, not within 2 units of the player and not within about 1.6 units of any obstacle. Cubes are bright emissive and randomly colored from yellow, pink/red, purple, mint green, and cyan. Each cube is about 0.72 on a side, floats up and down slightly, rotates continuously, and casts a shadow. A cube is collected automatically when the player comes within about 0.9 units. Remove it, award 10 times the current combo, increment collected count, increase combo by 1 up to x9, add 1.25 seconds to the timer capped at 60, show a brief pill-shaped message such as "+10 combo x2", and immediately spawn a replacement cube. Also, after 8 seconds, spawn another cube if fewer than 10 are present. The timer counts down in real time, with occasional brief messages at 50, 40, 30, 20, and 10 seconds remaining. End the round at zero seconds and stop movement/gameplay.

Build a clean HTML HUD over the 3D scene. Across the top, show translucent dark rounded panels with cyan borders: left brand panel reading "CUBE RUSH" and "collect before the clock"; right-side stat panels showing SCORE, COMBO, and SECONDS, initially 0, x1, and 60. Use bold white typography with muted light-blue labels, blur/glass styling, and responsive sizing for small screens. At the bottom center show the hint "WASD / arrows · move with the on-screen stick on mobile". Before play, display a large centered translucent dark-blue rounded start card with the title "Cube Rush", text "Chase the bright cubes, build your combo, and clear the arena before the 60-second timer hits zero.", and a bright cyan-to-blue button labeled "Start collecting". Hide the card while playing. When the timer expires, show the card again with the score as its heading (for example "120 points"), explanatory completion text such as "You cleared 8 cubes. Start another run and beat your score.", and a "Play again" button; preserve the HUD showing the final values. Make the interface responsive and touch-friendly, with rounded glass panels and soft blue shadows. Do not add enemies, weapons, lives, or leaderboard systems; the implemented game is solely about navigating and collecting cubes before the countdown ends.
