Vents 0.0.2

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 small playable 3D physics-fighting prototype titled “Vents 0.0.2.” Use Three.js or an equivalent real-time 3D engine with a fixed, high third-person/isometric camera: perspective view from roughly (0,17,19), looking at the center of the arena, with a muted blue-gray industrial scene, soft shadows, ambient fog, and no camera following the player. The entire play space is a rooftop test arena made from several separated thin gray metal roof plates with gaps around them, so players can fall off. Build a main 18 x 9 roof plate, additional plates toward the north (-Z), south (+Z), and east (+X), dark low perimeter walls along the back and left, and a shorter wall on the right. Include visible oversized industrial vent props: four dark horizontal cylindrical pipes across the rear/middle area, three raised rectangular vent housings with darker caps, and several narrow metal floor strips. Use simple low-poly geometry and industrial materials in gray, dark charcoal, blue-gray, and edge-metal tones.

Spawn four crude cartoon humanoid test characters on the roof. Each should be made from simple rounded low-poly spheres/capsules: a large rounded body, smaller head, two tiny dark eyes, capsule arms and legs, and spherical hands. Color them blue, red, yellow/gold, and green. The blue character is the human-controlled player and the other three are simple AI bots. Label them conceptually as YOU, BOT RED, BOT GOLD, and BOT GREEN, but do not require world-space nameplates. Characters should have basic gravity, friction/deceleration, jumping, body collision separation, knockback, stun, grabbing, and fall/death behavior. Keep the physics intentionally prototype-like and slightly ragdoll-ish: punches can launch opponents and add rotational tumbling.

The goal is a last-character-standing round. The player moves with WASD, jumps with Space, punches with left mouse button, grabs with right mouse button, ducks with E, and uses Q while holding someone to throw/release them with forward and upward force. Show the same control hint in the HUD: “WASD move · SPACE jump · LMB punch · RMB grab · E duck · Q raise arms / throw” and a second line explaining “Blue is you. Others are crude test bots. Fall off the roof to lose the round.” Movement is faster when standing and slower while ducking. Only allow jumping while grounded. A punch should target the nearest living opponent within short range (about 2.25 units), apply horizontal knockback plus upward force, briefly stun them, and have a short global action cooldown. A grab should target a nearby opponent (about 1.85 units), hold them beside the player, and Q should throw the held target. Prevent repeated grab/punch actions while stunned. Bots should pursue the nearest living opponent, punch when close, occasionally grab, and occasionally jump.

A character is eliminated when they fall beyond the roof boundary (roughly outside x/z ±13 or below y -3), becoming invisible and no longer participating. Resolve simple horizontal body overlap between living characters. When one or zero characters remain, end the round and display a large centered overlay reading “<NAME> WINS” or “NOBODY WINS,” then automatically reset after about 3.2 seconds, respawning all four at fixed positions and incrementing the round number.

Add a minimal dark HUD over the canvas. At top left show “VENTS 0.0.2” in spaced monospace lettering and beneath it a small status line such as “round 1 · alive 4/4 · prototype physics online.” At top right show “VENTS / TEST BUILD” and, after completion, “round complete.” At bottom left show the bordered translucent help panel with the control instructions. Use a nearly black page background, light gray monospace typography, subtle text shadows, and a large white center victory banner with letter spacing. The gameplay should feel like an unfinished technical test build: sparse interface, stark industrial rooftop, basic colored blob characters, overhead framing, and no menus or extra features.
