Moonbound Maker

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 responsive, canvas-based 2D arcade rocket-building game titled “Moonbound Maker.” Render the whole game in a full-window HTML canvas with a dark navy-to-blue space/atmosphere background, a subtle warm orange horizon near the bottom, many small white stars, and bold rounded system-font UI. Keep the style clean, colorful, and mobile-friendly: dark blue rounded panels with lighter blue borders, white headings, muted blue secondary text, mint-green progress bars, and gold coin values.

The game has three screens: hangar, rocket shop, and flight control. Persist a player state with 180 starting coins, score 0, best score 0, launch count, and five rocket component levels, all starting at level 1: body, engine, fuel, fins, and capsule. Display a gold diamond-like coin icon and current coins in the upper-right.

Hangar screen: header text “MOONBOUND MAKER” and subtitle “Build it big. Launch it farther.” Show “ROCKET POWER,” a large numeric power value, and a mint progress bar capped visually at 180. Base rocket power is 35; add each selected component’s power bonus. Use these upgrade data exactly: body Tin Body +0, Steel Body +18 for 90 coins, Titanium Body +42 for 220; engine Bubble Engine +0, Turbo Engine +28 for 120, Quantum Engine +65 for 280; fuel Small Tank +0, Cryo Tank +20 for 100, Moon Fuel +50 for 240; fins Paper Fins +0, Alloy Fins +12 for 70, Ion Stabilizers +32 for 180; capsule Tiny Pod +0, Lunar Pod +18 for 160, Moon Lab +40 for 360. Draw a centered stylized white rocket in the middle/lower sky: rounded pointed nose with a blue window, pink-red band, pale blue body stripe, pink triangular side fins, gray lower engine, and no flame while idle. Place two large side-by-side navigation cards around the upper-middle: “SHOP / Upgrade rocket parts” and “LAUNCH / Fly toward the Moon.” At the bottom show five compact component cards listing each part, the currently equipped upgrade’s first name, and “LV 1/2/3” in mint. Also provide a wide bottom button reading “LAUNCH TO SPACE” with “Earn coins and test your upgrades.”

Shop screen: retain the same background and coin display. Header “ROCKET SHOP,” subtitle “Install better parts before launch.” Add “Coins pay for permanent upgrades.” Below, show five stacked rounded rows for Body, Engine, Fuel, Fins, and Capsule. Each row displays the current item and, if another level exists, “NEXT: [next item]”, its power increase and cost, plus a right-side BUY button. Make BUY green/active only when affordable and muted blue/disabled-looking otherwise; show “MAXED” when the final level is equipped. Clicking an affordable BUY button deducts the cost and permanently advances that component one level. Add a wide bottom “← BACK TO HANGAR” button.

Flight control screen: header “FLIGHT CONTROL,” subtitle “Keep the rocket climbing to reach the Moon.” Draw a pale circular Moon with a few translucent crater spots in the upper-right. Show “ALTITUDE,” current altitude in whole km, “TARGET 384,400 km,” and a mint altitude progress bar that fills based on altitude divided by 384400. Draw the rocket centered vertically according to altitude, initially around the lower-middle and moving upward as altitude rises; show a yellow/orange animated exhaust flame while flying. Show a bottom dark panel with “SPEED,” current speed as a percentage capped visually at 100%, and an instruction message initially “Tap anywhere to ignite,” changing to “BOOSTING!” after ignition. Put “BOOST” as a centered label near the bottom and a red wide “ABORT FLIGHT” button below it.

Launching resets altitude to 0, speed to 0, fuel to 100, status to ready, and message “Tap anywhere to ignite,” then switches to flight control. Clicking/tapping anywhere in the flight area (except the abort region) changes ready to flying; while flying, pointer movement gives an additional direct speed boost and creates small orange/yellow exhaust particles. Keyboard Space or Enter starts a launch from the hangar and ignites a flight; Escape returns to the hangar. Clicking the bottom abort area returns to the hangar. While flying, update speed using rocket power (accelerate by (power*0.008 + 0.11) per frame-scaled unit and apply slight drag), and increase altitude based on speed and rocket power (altitude += speed * power * dt * 2.6). Add intermittent small glowing orange/yellow particles behind the rocket. When altitude reaches 384400 km, set status to won, display “MOON REACHED!”, award 120 coins, increment score, and update best score. Clicking after a won flight returns to the hangar. Do not add enemies, combat, fuel depletion, obstacles, extra menus, or unimplemented gameplay systems.

Use responsive coordinates based on window width and height, cap device pixel ratio at 2, and ensure pointer/touch interaction works on the canvas without scrolling. The rocket should be a simple vector/canvas illustration matching the described geometry rather than an external asset. Keep all UI text and colors close to the specified design: white headings, #071329-like deep navy, #0b1c43/#163f6f sky blues, pink-red rocket accents, mint #3de0a1-like progress highlights, and gold #ffd166-like coin/speed accents.
