Crater Run

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 playable third-person 3D game titled "Crater Run". Use a perspective camera following a small yellow/gold capsule-shaped astronaut-like character from behind and slightly above, with a dark blue-gray visor on the front. The player starts on a broad flat green grassy clearing at position near the south end of the play area and must move straight across to the far/north side, passing a large crater in the center without falling into it. Use a clean low-poly style with soft shadows, simple materials, and a pale blue sky-colored background with atmospheric fog toward the horizon.

Build the environment as a roughly 34-by-34 flat green ground plane. In the center, create a prominent deep, very dark/black circular crater: a wide depressed cylindrical hole with a dark interior and a thick dark green-black torus-like raised rim around its opening. The opening should appear slightly oval from the camera view. Place several scattered blocky brown/orange rock formations around the clearing, with greenish top surfaces, including rocks around the left/right sides and beyond the crater; use varied positions, rotations, and scales. Enable directional sunlight, ambient/hemisphere lighting, cast shadows, and soft shadow receiving on the ground and rocks.

The player is a rounded capsule, gold/yellow, standing upright and casting a shadow. Start it around the front/south side of the crater. Provide third-person movement using WASD or arrow keys, with movement speed around 4.2; Shift enables sprint, and Space jumps. Include touch-friendly on-screen virtual controls for mobile devices. The character has gravity and can jump, but if it drops below the crater depth (roughly y=-3.1), count that as a fall. On falling, increment the fall counter, show a centered dark translucent message panel saying "You fell into the crater.", then reset the player to the original starting position after a short delay. The reset button in the message panel should also return the player to the start.

The finish condition is reaching the far side, represented by moving past the northern boundary (z less than about -10.8). When successful, stop normal completion logic, update the objective text to "Safe on the far side", and show a centered message "You made it across!" with a rounded gold "Try again" button. While playing, update the objective based on player position: on the starting side show "Approach the crater", in the middle danger area show "Crossing the danger zone", and near the far side show "Almost there". The HUD is an always-visible overlay in light cream text with dark text shadows: top-left large spaced uppercase title "CRATER RUN" and subtitle "Cross the clearing without falling in."; top-right bold text "Falls: 0" (updating as needed) and the current objective below it. On desktop, show the bottom-center hint "WASD / arrows to move · Shift to sprint · Space to jump"; hide this hint on coarse/touch pointers. Use a full-screen canvas, no scrolling, and a responsive camera/renderer that adapts to window resizing.
