MathVerse

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 3D educational adventure prototype titled “MathVerse: Battle of Numbers.” Use a third-person camera following a low-poly armored warrior hero in a small enclosed training ground. The scene should have a bright sky-blue background with light fog, soft shadows, simple stylized low-poly geometry, and an orthographic-feeling arcade adventure presentation (the implementation may use a perspective camera). Build the environment as a rectangular green training field bounded by dark blue walls, with a narrow lighter path leading toward the far end. Place several large low-poly gray resource rocks around the field. At the far end, separate a purple-floored boss arena with dark blue side walls. Use a low-poly fantasy warrior character for the player and a large low-poly demon/monster as the Number Beast boss; both should cast and receive shadows and have idle animations where available.

Start on a full-screen main menu over the 3D scene. The menu is a centered dark translucent rounded card with the yellow title “MathVerse,” subtitle “Battle of Numbers,” the message “Turn math into your superpower,” and three large buttons: yellow “PLAY LEVEL 1,” blue “LEVELS,” and blue “SETTINGS.” Include the small footer text “A small educational adventure prototype.” The LEVELS button should show a notification that Level 1 is ready and more worlds are coming soon. The SETTINGS button should show the controls: WASD/arrow movement, Space to jump, and drag to look.

When PLAY LEVEL 1 is selected, hide the menu and begin exploration. Show a top HUD with a PLAYER HP bar initialized to 100/100 and a rewards display initialized to coin 0 and XP 0. Show an objective card saying “Explore the training grounds and find the Mathematical Gate,” plus a bottom hint: “WASD / arrows move · Space jumps · drag to look · reach the gate.” Let the player freely move and jump through the training ground with WASD or arrow keys, Space for jumping, and mouse/touch drag for camera look. Put a large purple Mathematical Gate across the path near the far side, with a glowing gold rectangular rune/beam in front of it. The gate begins closed.

When the player reaches the gate area (within roughly three units along the path and near the center), open a centered dark translucent question card titled “MATHEMATICAL GATE,” with the prompt “Solve the question to unlock the gate!” Ask the fixed multiplication problem “24 × 6 = ?” and present four answer buttons: 124, 134, 144, and 154. On a wrong answer, keep the card open and display “TRY AGAIN!” with an explanation that 24 × 6 means 24 added 6 times = 144. On the correct answer, display “CORRECT!”, show a “GATE UNLOCKED!” banner, hide the glowing rune, raise/open the purple gate, and change the objective to “Enter the boss arena and face the Number Beast.”

After the gate is open, walking into the far arena (past approximately the z=-9 threshold) starts the boss encounter. Display a centered top boss card labeled “NUMBER BEAST” with a red boss HP bar at 100/100, show a “BOSS BATTLE!” banner, and change the objective to “Answer correctly to defeat the Number Beast.” Open a centered boss question panel with the heading “NUMBER BEAST,” the line “Mathematics is your weapon!”, a multiple-choice arithmetic question, four answer buttons, and the text “Basic Attack · 20 damage.” The player answers questions rather than performing a conventional attack.

Implement three boss difficulty phases based on the boss’s remaining HP: phase 1 while above 70 HP uses randomly generated addition, subtraction, or multiplication questions (addition operands approximately 10–39 and 5–24, subtraction operands approximately 25–59 and 5–24, multiplication operands approximately 3–10 and 2–9); phase 2 from 40 through 70 HP uses subtraction or multiplication with the ranges used by the game; phase 3 at 40 HP or less uses division questions where the dividend is constructed to produce an integer answer. For every question, provide four shuffled choices consisting of the correct answer plus distractors formed by adding 2, subtracting 2, and adding 5. The panel should identify the current phase and say “Choose your Basic Attack answer.”

For each boss answer, lock input briefly. A correct answer reduces Number Beast HP by 20, shows a “-20 HP” toast and the feedback “CORRECT! Math power hits!”; an incorrect answer reduces player HP by 10, shows a “-10 HP” toast and feedback “WRONG ANSWER!” followed by an explanation of the correct answer. Update both HUD bars after each answer, briefly close the question card, then ask another question unless the fight has ended. Play a hit reaction animation for the boss on correct answers if available and a punch animation on incorrect answers if available.

If the boss reaches 0 HP, award 25 coins and 100 XP, hide the boss UI, show a centered victory card reading “BOSS DEFEATED!”, “MATHEMATICS MASTERED!”, and “+100 XP · +25 Coins,” and provide a “NEXT LEVEL” button. The button should only announce “WORLD 1 · LEVEL 2 COMING SOON,” then reset to the exploration state for another run. If player HP reaches 0 first, show a centered pink-accented “TRY AGAIN” card with the message “The Number Beast got lucky. Your math power is still strong.” and buttons “RETRY BOSS” and “MAIN MENU.” Retry should reset the boss and player to 100 HP and return to the boss encounter; Main Menu should return to the original title screen. Preserve the clean rounded-card UI style: dark navy translucent panels, yellow headings and primary actions, pale blue secondary buttons, large bold text, compact HP bars, and subtle shadows. Keep the experience as a single Level 1 prototype; do not add unshown levels, weapons, inventories, or extra mechanics.
