Four Keys

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/collection game titled “Four Keys.” The player controls a simple rounded capsule-shaped blue-gray humanoid avatar inside a dark, abandoned modular building. Use an over-the-shoulder/third-person camera that follows the player at about 5.8 units distance, with a centered small circular crosshair. The environment is a rectangular building approximately 16 units wide by 12 units deep: a gray floor, dark ceiling, outer walls made from repeating 2-meter building-kit wall sections, and a centered doorway in the south wall. Place a visible exit door at the south wall doorway. Add two interior wall partitions: one running around x=-2 from z=-2 to z=2, and another running around z=0 from x=2 to x=6, creating rooms/corridors. Add four brown crates as abandoned clutter near (-5,-3), (5,4), (5,-4), and (-5,4), with the latter three/four at varied scales. Use a dark blue-black background and fog, subdued gray-blue materials, warm directional lighting, cool fill lighting, and real-time shadows for a moody abandoned-building atmosphere.

The goal is to find all four collectible keys and then leave through the south exit. Place exactly four rotating, gently bobbing key pickups at approximately (-5,4.1), (5,4.2), (5,-4.1), and (-5,-4.1). Keys should be collected automatically when the player comes within roughly 1.15 units; make the key disappear, increment the counter, and show a temporary bottom-center message. The HUD at the upper left must be a translucent dark rounded panel with the title “FOUR KEYS,” the counter “Keys found: 0 / 4” (updated as keys are collected), and instructions: “Explore the abandoned building. WASD / arrows to move · Shift to run · Space to jump Mobile: use the on-screen joystick and jump button.” Show temporary pill-shaped status messages such as “Find all four keys. The exit is on the south wall.”, “Key found. 3 remaining.”, and after the fourth, “All keys found — unlock the exit!” The exit must only complete the game after all four keys are collected and the player approaches the south doorway/door at approximately (0,0,-6.4). On success show a full-screen dark translucent overlay with a centered card, gold heading “Exit unlocked,” text “You found all four keys and escaped.” and a “Play again” button that reloads/resets the game.

Movement must support keyboard WASD and arrow keys, Shift for running, Space for jumping, and touch/mobile controls with an on-screen joystick and jump button. Include gravity and collision with the floor and building geometry; the avatar starts near (0,0.35,4.3). Use a restrained low-poly/asset-kit visual style, with the rounded blue-gray player body, gray floor, dark walls/ceiling, crates, and key models. Keep the camera and interface responsive to window resizing and mobile screens.
