Skybound Steps

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-based first-person 3D parkour game titled “Skybound Steps.” The player starts on a chain of seven small floating islands suspended in a bright blue, foggy sky/void and must jump from island to island, collect all six glowing crystals, and reach the full route. Use a Three.js-like 3D scene with a perspective FPS camera, mouse/touch drag to look, WASD or arrow-key movement, Space to jump, and Shift to sprint. Give the player gravity and jumping physics; falling below the world resets them to the launch island with a short “Back to the launch island” notification.

Build the route as seven islands arranged progressively forward and upward along the negative Z direction: island 1 at (0,0,7) radius 7, island 2 at (0,1.2,-5) radius 5.1, island 3 at (7,2.7,-16) radius 4.5, island 4 at (-3,3.8,-27) radius 4.2, island 5 at (-12,5.2,-36) radius 4.7, island 6 at (-4,6.7,-47) radius 4.3, and island 7 at (8,8.3,-57) radius 5.1. Each island should look like a stylized low-poly floating landform: a dark blue-gray faceted rock/conical underside, a thin green grass-colored polygonal top, and a glowing cyan rim around its edge. Add a few decorative low-poly rocks around the route, and soft stylized clouds far below and around the islands. The sky should be blue with atmospheric fog, strong soft shadows, cool ambient hemisphere lighting, and a directional sun.

Place exactly six collectible luminous cyan/white crystals at these route positions: (0,1.05,3.2), (0,2.25,-5.5), (7,3.75,-16), (-3,4.85,-27), (-12,6.25,-36), and (-4,7.75,-47). Make each crystal visibly glow and disappear when the player comes within about 1.5 world units. Track crystal collection from 0/6. Detect island progress when the player is near an island and at approximately its height; increase the island counter as progressively later islands are reached, displaying Islands 1/7 through 7/7. When all six crystals are collected, show the message “Route complete — you own the sky.” Show short centered notifications for island milestones (“Island N reached”) and “Crystal collected.”

Use a minimal dark translucent HUD over the game. At the upper left, show a rounded panel with cyan uppercase title “SKYBOUND STEPS” and subtitle “Parkour across the void.” At the upper right, show “Crystals 0/6” and “Islands 1/7” with the live counts. Put a small white circular crosshair with a cyan glow at screen center. Along the bottom center show the control hint: “WASD / arrows move · Space jump · Shift sprint · drag to look · collect every crystal.” Notifications should appear near the upper center and fade out. Use a dark navy HUD aesthetic with pale blue text, rounded borders, subtle backdrop blur, and responsive safe-area positioning. Do not add weapons, enemies, health, timers, or other gameplay systems; the core experience is first-person jumping across the seven floating islands and collecting every crystal.
