Orbit Quest

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 kid-friendly 3D browser space exploration game titled “Orbit Quest,” viewed in a third-person chase camera behind a small stylized spaceship. Use a dark navy/black starfield with hundreds of small bright stars, subtle exponential fog, soft blue ambient lighting, and warm sunlight. Populate the route with low-poly/stylized space-kit-like models: a large blue-green Earth near the starting area, a gray Moon, orange-red Mars, a large striped/tan Jupiter, a glowing golden Sun, and a field of scattered irregular asteroids made from small and large rocks. Bodies should slowly rotate. The spaceship should be a small colorful cartoon spacecraft, and the camera should follow smoothly from behind and above it, looking forward along its travel direction. The initial view should prominently show Earth filling the lower foreground, with the ship near it, while the route extends forward into space.

The core loop is flying through glowing checkpoints and answering science questions. Start the player at Earth with fuel 100 and score 0. The ordered route is: Moon, Mars, Asteroid Belt, Jupiter, Sun Observatory, then Return to Earth. Place the checkpoints along a navigable 3D course approximately at Moon (0, 2.4, -14), Mars (18, 2.8, -28), Asteroid Belt (-18, 3, -42), Jupiter (18, 4, -60), Sun Observatory (0, 5, -80), and Earth return (0, 3, 5). Each checkpoint is an animated floating glowing sprite/ring: the current destination is bright yellow/white and larger, while later destinations are dim blue-gray and smaller; only the current and future checkpoints are shown. Add floating dark pill-shaped world labels such as Earth, Moon, Mars, Asteroid Belt, Jupiter, Sun Observatory, and Return to Earth, with the active destination highlighted yellow.

Control flight with WASD or arrow keys: left/right turn the ship, up/W thrusts forward, down/S thrusts backward, and Space boosts while moving forward. Apply acceleration, speed limits, drag, smooth vertical leveling, and clamp the ship within the play area. Normal forward thrust has a maximum speed around 14; forward boost raises it around 24. Fuel drains continuously while moving, around 1.65 per second normally and 4.2 per second while boosting. End the mission immediately if fuel reaches zero. Also provide touch-friendly on-screen controls: left, up, right buttons and a wide orange-yellow BOOST button, using press-and-hold behavior.

When the ship comes within roughly 3.15 units of the active checkpoint, pause/slow flight and open a centered modal checkpoint quiz with a dark translucent backdrop and a rounded blue gradient card. Each quiz has four large white answer buttons and is selectable by mouse or touch. Use these exact questions, answers, correct choices, and educational facts in order: at Moon: “Which planet is third from the Sun?” answers “Earth”, “Mars”, “Venus”, “Jupiter”; correct Earth; fact “Earth is third from the Sun: Mercury, Venus, Earth.” At Mars: “Why do astronauts feel lighter on the Moon than on Earth?” answers “The Moon has weaker gravity”, “The Moon has more air”, “Space suits make them float”, “The Sun pulls them up”; correct the weaker-gravity answer; fact “The Moon has less mass than Earth, so its gravity is weaker.” At Asteroid Belt: “Most asteroids in our solar system orbit between which two planets?” answers “Mars and Jupiter”, “Earth and Mars”, “Venus and Earth”, “Saturn and Uranus”; correct Mars and Jupiter; fact “The main asteroid belt is between Mars and Jupiter.” At Jupiter: “What keeps planets moving around the Sun instead of flying away?” answers “Gravity”, “Clouds”, “Magnets in the sky”, “The Moon”; correct Gravity; fact “The Sun’s gravity pulls on planets and bends their paths into orbits.” At Sun Observatory: “What kind of object is the Sun?” answers “A star”, “A planet”, “A moon”, “An asteroid”; correct A star; fact “The Sun is a star — a huge ball of hot glowing gas.” At Return to Earth: “What is one reason Earth is friendly to life?” answers “Liquid water”, “No gravity”, “It is the biggest planet”, “It has no atmosphere”; correct Liquid water; fact “Earth has liquid water, an atmosphere, and the right distance from the Sun.”

For each correct answer, award +100 score and +28 fuel, capped at 140 fuel. For each wrong answer, deduct 22 fuel. After either answer, show a temporary prominent feedback message with the result and the educational fact, mark the stop visited, and activate the next checkpoint. The mission is successful only after all six stops are completed, the player has returned to Earth, and the final score is at least 400. Show a mission-complete overlay with the final fuel and score when won. If fuel reaches zero, or the player returns with less than 400 points, show a mission-ended overlay explaining the reason and a “Play again” restart button. Restart resets the route, fuel to 100, score to 0, visited stops, ship position/orientation, velocity, and overlays.

Build a polished responsive HUD over the 3D scene. At the top, show a rounded translucent navy panel with “FUEL” and a large numeric fuel value on the left, a long rounded horizontal fuel bar in the middle using a green-to-yellow gradient that turns red/orange when fuel is below 25, “SCORE” and the score value on the right, and a centered/below route readout such as “Earth → Moon” or “Moon → Mars”; after completion show “Return complete.” Include a lower-left help panel reading essentially “Orbit Quest / Fly to the glowing ring, answer the science question, and return to Earth before fuel runs out. / WASD / arrows steer · Space boosts,” but hide this help panel on narrow mobile screens. Show temporary centered mission messages near the upper-middle of the screen, such as the initial instruction to fly to the glowing Moon checkpoint. Use rounded glass-like panels, bright white text, pale blue labels, yellow highlights, and soft shadows throughout. Ensure the quiz and end overlays are accessible modal layers above the HUD and that the game remains playable with keyboard, mouse, and touch controls.
