Crimson Rosekeep

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 3D third-person exploration game titled "Crimson Rosekeep". The player controls a small stylized cloaked vampire explorer in a moonlit castle environment. Use a behind-the-character third-person camera with mouse or drag look, WASD or arrow-key movement, and Space to jump; movement speed is about 3.2 and the character has gravity and jump motion. Start the player at the back of a rose courtyard around position (0, 0, 6.5), looking toward an open castle keep. The core goal is free exploration of the rose courtyard and open castle halls; there are no enemies, combat, collectibles, score, timer, health, or win condition.

Build a dark gothic castle keep from modular stone castle pieces. The main keep occupies the rear of the scene, with a rectangular layout roughly x=-5..5 and z=-2..-7: outer north/rear and side walls, a front facade at z=2, side towers at the four corners, upper wall sections, tower windows, and pointed/high tower roofs. The front facade should have a large open central archway into the keep. Inside, include wall dividers creating multiple open hall/room areas and three interactive dark wooden doors: one around the left inner divider near (-1.8, 0, -3.5), one around the right inner divider near (1.8, 0, -5.5), and one at the rear/crypt near (0, 0, -7). Each door is a dark rectangular slab with a small gold ring handle. Doors begin closed, can be clicked with the mouse to toggle open/closed, and when opened swing/rotate visibly about 0.72*pi radians. Make the click target generous enough to select the door. Put a "Reset Doors" button in the upper-right HUD that closes all doors.

In front of the keep, make a broad rectangular rose courtyard, with a dark ground plane extending beyond it. Add a decorative gate at the far/front edge around z=5, two benches near x=-3 and x=3 facing inward, and stone rose-statue bases near x=-2.4 and 2.4 around z=1.2. Populate the courtyard with small handmade rose bushes: dark green stems/leaves and clusters of crimson red flowers, including a row near the gate and flowers on the statue bases. Add three hanging wuxia-style red lanterns with gold caps and tassels, two near the courtyard entrance sides and one farther into the courtyard. Add glowing crimson/red window panels on the castle facade and tower sections.

The visual style is atmospheric, low-poly/modular gothic fantasy at night: nearly black navy-purple background and fog, dark charcoal ground and gray-blue stone, deep burgundy doors, vivid crimson roses/windows/lanterns, and small antique-gold details. Light the scene with cool blue moonlight from above/left, soft blue ambient fill, strong red light washing the keep, and warm red-orange courtyard glow. Use shadows, subtle exponential distance fog, reflective/emissive materials on red glass and lanterns, and a cinematic dark exposure. The player is a simple silhouette made from a dark six-sided cone-like cloak/body with a small muted red-brown spherical head.

Overlay a fixed dark burgundy translucent HUD panel in the upper-left, bordered with muted crimson and styled in a serif/Georgia-like font. It must display the title in uppercase/spaced lettering, the text "Explore the rose courtyard and the open castle halls.", and the controls text "WASD / arrows move · mouse or drag looks · Space jumps · click a door to open or close it." Place the burgundy "Reset Doors" button upper-right. Include a bottom-center door hint reading "Click the door to open or close it" with a crimson border, but keep it hidden unless needed. Keep the game full-screen, with no visible crosshair or other status meters.
