Skyline Sprint

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 third-person 3D platforming game titled “Skyline Sprint.” Use a dark navy sky/background (#071329) with atmospheric fog extending through a vertical floating obstacle course. The camera is a perspective third-person camera following a small stylized yellow/gold capsule-shaped runner, with a dark blue visor on its front. Use soft shadows, warm directional sunlight, cool hemisphere lighting, and a polished low-poly/material look with blue platforms, bright cyan glowing top surfaces, pink accents available for the environment, and luminous gold coins.

The game begins with a centered dark translucent glass-like panel with a thin light border and rounded corners. It says “Skyline Sprint,” then “Grab the coins across the moving platforms.” and has a large rounded yellow “Start Run” button. While playing, show a fixed HUD: upper-left dark translucent rounded panel reading “COINS 0 / 11” (updating as coins are collected), and upper-right help panel reading “WASD to move,” “Space to jump · Shift to run,” and “Mobile joystick + jump button supported” (hide this help panel on narrow mobile screens). The UI should use a clean system/Inter-like sans-serif font, white text, pale blue secondary text, and yellow accents.

Build a short ascending route of floating rectangular platforms. The starting platform is centered at approximately (x=0, y=0, z=6), about 7.4 wide by 3.8 deep. The player starts above it at (0, 1.5, 6). Place the following platforms in order toward increasingly negative z and increasing height: platform 1 at (-4.5, 2.0, 2.0), 3.4 by 2.4; platform 2 at (1.5, 3.2, -2.0), 3.3 by 2.2, moving side-to-side along x with range 3.0 and speed 1.2; platform 3 at (5.0, 4.8, -6.0), 3.8 by 2.4; platform 4 at (0.5, 6.3, -9.8), 3.2 by 2.1, moving along x with range 3.6 and speed 1.55; platform 5 at (-4.2, 7.8, -13.5), 4.5 by 2.7; platform 6 at (1.5, 9.3, -17.5), 3.2 by 2.1, moving along z with range 2.8 and speed 1.1; platform 7 at (5.1, 10.7, -21.5), 4.6 by 2.6; platform 8 at (0, 12.2, -25.5), 3.5 by 2.2, moving along x with range 4.2 and speed 1.45; platform 9 at (-5.0, 13.6, -29.0), 4.6 by 2.6; and a final finish platform at (0, 15.1, -33.0), 6.4 by 3.0. Platforms are blue box meshes with slightly raised bright cyan top plates. Moving platforms oscillate sinusoidally around their base positions.

Place exactly 11 collectible gold coins, one per platform/route stop: (0, 1.35, 6), (-4.5, 3.25, 2), (1.5, 4.45, -2), (5.0, 6.05, -6), (0.5, 7.55, -9.8), (-4.2, 9.05, -13.5), (1.5, 10.55, -17.5), (5.1, 11.95, -21.5), (0, 13.45, -25.5), (-5.0, 15.0, -29), and (0, 16.5, -33). Coins should be short thick gold cylinders oriented so their circular face is visible from the route, emissive/glowing, slowly rotating, and bobbing vertically. Collect a coin when the player comes within a small radius; make it disappear and increment the HUD counter. The run is complete immediately when all 11 coins are collected, showing a centered panel titled “Run complete!” and text “You collected all 11 coins.” with a “Run it again” button.

Use WASD or arrow-key movement, Space to jump, and Shift to run. Support the control system’s third-person movement, gravity, jumping, slope limit, and mobile joystick/jump controls. The runner should be able to traverse and jump between elevated platforms. If the player falls below y=-5, end the run with a centered panel titled “Try again” and text stating how many coins were collected out of 11, with a “Restart” button. Resetting restores the player to the start, makes all coins visible and uncollected, resets the counter, and returns to active gameplay. Keep the scene free of enemies, weapons, timers, lives, or other unshown mechanics.
