Ciudad Libre

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-playable 3D third-person exploration game titled “Ciudad Libre,” with all visible interface text in Spanish. Use a bright, simple low-poly/blocky city aesthetic with Three.js-style rendering: pale blue sky background with atmospheric fog, soft hemisphere daylight plus a strong directional sun and shadows, green grass ground, dark gray roads, and small pale-yellow lane markings. Build a large bounded square city area approximately 120 by 120 units, with a cross-shaped road layout: a wide road running east-west through the center, another running north-south, plus additional roads near the south and west edges. Place four stylized commercial block buildings around the central roads (roughly at northwest, northeast, southwest, and southeast positions), using blocky city-kit architecture. Keep the scene open and uncluttered beyond these buildings, roads, grass, and lane markings.

The player is a blocky humanoid character initially positioned on foot near the central/southeastern road, with a third-person follow camera behind and above the character. The camera should smoothly follow the current controlled target and look toward its upper body. The player can freely walk in four directions using WASD or a virtual joystick, with movement speed around 6 units/second, optional faster movement while holding Shift, and rotation to face the travel direction. Constrain movement to the city bounds. Press Space or the on-screen SALTAR button to jump; implement simple gravity and landing back on the ground. Do not add combat, enemies, health, weapons, or other systems.

Include one parked stylized toy SUV near the player. When the player is close enough to it (within about 5 units), pressing the Spanish ACCIÓN button boards the SUV: hide the humanoid, switch control to the car, and make the camera follow the SUV. While driving, WASD or the joystick controls throttle and steering: W/S accelerate forward/backward and A/D turn, with smooth acceleration and a capped movement speed around 13. Keep the SUV inside the city bounds. The action button becomes BAJAR while driving; pressing it exits the SUV, makes the player visible again, and places the player just beside the vehicle. The SUV should visibly rotate as it steers and cast shadows.

Place a glowing, rotating yellow circular mission marker at approximately the far southeast/northeast diagonal location relative to the starting area (world coordinates around x=23,z=-23). On foot, when near this marker (within about 4 units), pressing ACCIÓN completes the only mission, changes the mission state to delivered, awards
