Shadow Prime Arena

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 browser game titled “Shadow Prime Arena,” a solo low-poly 3D top-down arena battle. Use a dark navy sci-fi/fantasy presentation with a perspective camera looking down from behind/above the player, centered on a circular arena. The scene should have a very dark blue background and fog, soft bright hemisphere lighting, a strong white directional light with shadows, and a cool blue rim light.

Build the arena as a large flat dark-blue circular cylinder/platform, with a thin glowing turquoise torus ring around its edge. Place 12 small chunky cube-like cover blocks evenly around the perimeter; alternate their dark blue and muted purple colors and rotate them around the circle. The arena floor and blocks should cast/receive soft shadows.

The player is a small blocky humanoid character loaded from or resembling a simple Kenney-style block character, standing near the arena center (initially toward the lower/front side), with a slight purple tint for the default hero. Use smooth idle animation if available. Provide four selectable hero buttons: “Сіріус” with the role text “тіні • контроль,” “Наджия” with “отрута • шкода,” “Норі” with “ривок • гак,” and “Венді” with “щит • підтримка.” Sirius is selected initially. Selecting a hero changes the displayed hero/role and tints the player: Sirius purple, Nadiya lime green, Nori cyan, Wendy pink. Based on the implemented mechanics, the hero selection primarily changes tint and displayed identity; Nadiya’s attacks additionally deal 2.5 damage instead of the normal 1 damage, while the other heroes deal 1 damage.

Enemies are simple low-poly red/pink capsule-like creatures with a glowing pale yellow/orange eye, dark red emissive shading, and shadows. Start with five enemies positioned randomly around the outer arena at radius 9–13, and continuously spawn another enemy about every 1.6 seconds, up to 8 simultaneous enemies. Each enemy has 2 hit points and a slightly varied movement speed around 1.15–1.95. Enemies continuously move directly toward the player, turn to face the player, and damage the player on contact range (within about 0.95 units) at 9 health per second. The player begins with 100 health. Defeat enemies to increase the victory counter; after 20 kills, stop the game and show a victory overlay. If health reaches zero, stop the game and show a defeat overlay. Do not add extra enemy types or abilities that are not described.

The attack is a basic ranged “shadow bolt.” When the player attacks, automatically target the nearest enemy, create a small glowing spherical projectile tinted to the selected hero’s color, launch it from about head height toward that enemy, and move it quickly at about 12 units/second. Attacks have a 0.36-second cooldown, projectiles expire after 1.5 seconds, and a projectile hitting its target within roughly 0.8 units applies the hero’s damage and removes the projectile. Use a visible orange/red circular attack button at bottom right labeled “АТАКА”; clicking/touching it attacks. Also support Spacebar for attacking. If there is no enemy or the game is over, attacking does nothing.

Support movement with WASD/arrow keys and a virtual left joystick/touch control suitable for mobile, using top-down movement speed around 6. The player should remain in the arena rather than jumping; use no jump mechanic. Keep the camera following/targeting the player in a top-down perspective with a moderate distance around 18.

Create a glassy, rounded HUD over the canvas in Ukrainian. At top left show a dark translucent rounded panel with cyan title “SHADOW PRIME ARENA” and subtitle “горизонтальна 3D-арена • соло-бій.” At top right show “Перемоги: 0 / 20” (updating the kill count), the selected hero and role such as “Сіріус • Контроль,” and a horizontal health bar initially full with a dark track and a cyan/green gradient fill that shrinks with health. Along the bottom left show the four rounded hero selection buttons, with the active choice outlined in bright cyan and slightly brighter blue. Put the attack button at bottom right. Use responsive mobile layout and preserve the dark blue, cyan, and warm orange visual palette.

When the game ends, display a centered dark translucent rounded modal with a large title: “ПЕРЕМОГА” and hint “Ти очистив арену Prime.” after 20 defeats, or “ТЕМРЯВА ПЕРЕМОГЛА” and hint “Спробуй іншого бійця або почни знову.” when the player dies. Include a mint-green “ПОЧАТИ ЗНОВУ” button. Restarting clears projectiles and enemies, resets kills to 0, health to 100, places the player back at the starting position, spawns five fresh enemies, and resumes play. Enter should also restart after game over.
