Starfall Relic

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 action RPG called "Starfall Relic" with an anime-inspired space fantasy aesthetic. The camera is a third-person follow camera positioned behind and above the player character at about 8 units back and 3.5 units up, with mouse-drag or right-side touch controls for camera rotation (yaw and pitch).

**Player Character:** A low-poly anime-style warrior with sword and spell abilities. The player model has idle, run, attack, and dodge animations. Starting stats: 100 HP, 80 mana, movement speed 7.1, dodge speed 16 with cooldown.

**Setting & Visuals:** A bright anime-style environment featuring:
- Gradient anime sky dome transitioning from deep purple-blue at top through violet to pink at horizon
- Two moons: large pink moon with glowing halo and smaller cyan moon
- Starfield background with 800+ tiny white stars
- Floating sparkle particles (220 pink dream sparkles scattered across the world)
- Dark purple-blue ground plane (70-unit radius circle)
- Space station hub area at Z=-8 with metallic sci-fi structures: large base building, geodesic dome (west), long house module (east), connector modules, all with cyan-blue emissive glow
- Elevated station pads in blue-purple metallic material with subtle emissive lighting
- A glowing cyan energy bridge (8 units wide, 48 units long) extending north from station at Z=1 to Z=46, with glowing rails on both sides and alternating pink/cyan crystal lamps along the path (8 crystals total)
- Alien ruins area at Z=82-106 with purple-tinted fantasy temple structures, scattered rock formations, and stylized purple-green trees
- Purple circular ruin platform (18-unit radius) and boss arena circle (9-unit radius at Z=100)
- Cherry blossom-style trees around station perimeter with pink-purple tint
- All geometry casts and receives shadows with soft PCF shadow mapping
- Fog extending from 38 to 170 units in dark blue
- ACES Filmic tone mapping at 1.05 exposure

**Lighting:** Hemisphere light (cyan sky 0x9cd8ff, dark blue ground 0x1a2030, intensity 1.45), directional sun light from position (14, 24, 8) with intensity 2.1 and 2048×2048 shadow map.

**Controls (Desktop):** WASD or arrow keys move, mouse rotates camera, left-click for light melee attack (plays sword slash animation, creates cyan arc slash effect, deals 28+ damage in 2.4-unit range), right-click casts ranged magic spell (costs mana, fires glowing cyan projectile sphere traveling at speed 18 that homes toward enemies), Shift or Space to dodge roll (dash at speed 16 with cooldown and brief invulnerability), E to interact with NPCs/objects, I to toggle inventory panel, 1 to consume health item (restores HP), 2 to consume mana item (restores mana), R to restart after victory.

**Controls (Mobile):** Left-side virtual joystick for movement, right-side drag for camera look, on-screen buttons for Slash, Spell, Dodge, Interact, and Bag (inventory).

**HUD Elements visible on screen:**
- Top-left: Red HP bar with current/max text (e.g. "100 / 100")
- Below that: Cyan mana bar with current/max text (e.g. "80 / 80")
- Checkpoint name display showing current respawn point (e.g. "Checkpoint: Dock Ring")
- Quest objective text centered at top showing current mission phase
- Interaction prompt appears when near NPCs or objectives (e.g. "Press E / Interact — talk to Archmage Lyra")
- Floating message text for pickups and events (2.4 second duration, fades out)
- Inventory panel (toggle with I key): shows health patches, mana cells, crystal status, and equipped gear list
- Death overlay with "Defeated — Respawning..." message
- Win overlay when quest complete
- Utility bar with Install App, Download Save, Load Save buttons
- Mobile: virtual joystick (left), action buttons (right), crosshair (center when not in touch mode)

**NPCs (4 total, standing idle with animations):**
1. Archmage Lyra - wizard model at station core (-1.8, 0.6, -6), purple-blue robes, talks about the mission to recover crystal from ruins
2. Captain Sol - warrior model at station area (3.2, 0.6, -11.5), gives advice about checkpoints and consumable items
3. Scout Mika - wizard model on bridge (-2.4, 1.23, 42), cyan-tinted robes, explains bridge crystals and ruin layout
4. Guardian Ren - warrior model at ruin entrance (6.4, 0.9, 86), purple-green tint, warns about boss mechanics
Each NPC has multiple dialogue lines that change based on quest progress. Interact radius 3.3 units. Press E when near to advance dialogue.

**Enemies (5 types, each with idle/walk/run/attack animations and AI chase behavior):**
1. Drone Skitter (enemySmall) - small alien at bridge area, 34 HP, speed 4.2, melee range 1.6, damage 11
2. Drone Flier (enemyFlying) - flying alien hovering at Y=3.2, 26 HP, speed 4.7, fires pink projectiles, damage 9, bobs up/down
3. Alien Sentinel (enemyTall, 2 instances) - tall aliens in ruin courtyard, 45 HP each, speed 3.7, melee range 1.7, damage 13

Enemies chase player within aggro range (20 units normal, 999 boss), path toward player when beyond attack range, play attack animation and deal damage when in range (melee enemies) or fire projectiles (boss, fliers). Projectiles are glowing pink spheres with point lights. Enemies take hit-flash effect when damaged, die when HP reaches 0 (model tips over, fades, disappears after delay).

**Pickups (bobbing items with rotation animation, collected on proximity <1.7 units):**
- Med Patch (health) - red glowing sci-fi pickup, restores 1 consumable health item, 2 placed in world
- Mana Cell - purple glowing tank pickup, restores 1 consumable mana item, 2 placed in world

- Starfall Crystal (large crystal at altar 0, 1.25, 101.5) - becomes visible after boss defeated, quest objective item
All pickups bob vertically (sin wave animation) and rotate continuously. Gear pickups add to equipment list shown in inventory.

**Checkpoints (3 glowing cyan crystal beacons, rotating slowly):**
1. Dock Ring at (0, 0.85, -1.5) - active at start
2. Bridge Span at (0, 1.2, 67) - mid-bridge
3. Ruin Gate at (0, 1.0, 88) - ruin entrance
Walk within 1.8 units to activate. Active checkpoint glows brighter cyan (scale 1.08), shows name in HUD. Player respawns here after death (3 second delay).

Phase 3: "Bring the crystal back to the station core pedestal" - return to station Z=-8, approach pedestal (radius 1.8), press E to restore crystal and win
Phase 4: "The station is powered. Press R or tap to play again" - victory screen displays, R key reloads game
