Dumpster Panic

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 first-person 3D arcade shooter called “Dumpster Panic,” set in a narrow low-poly nighttime urban alley. Use a Three.js-like 3D perspective camera with a dark navy-black background and fog extending down the alley. The player is an unseen first-person character, with the camera at about 1.65 units high, initially centered near the front of the alley and facing down its length. Let the player move freely within roughly x=-5.8..5.8 and z=-37..10, using WASD or IJKL; W/I moves forward relative to the camera, S/K backward, A/J left, and D/L right. Mouse movement while pointer-locked aims the camera, and arrow keys look left/right/up/down. On mobile, provide a translucent circular left virtual joystick for movement and a large red circular FIRE button on the lower right.

Build a long alley from wet-looking dark asphalt, tall dark blue-gray building walls on both sides, a far barricade, scattered small dark trash bags, subtle wall-brick details, and repeated thin yellow lane stripes down the center. Place six stylized green dumpsters along alternating left and right sides at progressively distant positions. Each dumpster should be a chunky green rectangular bin with a darker tilted lid, dark rim, and small wheels. Illuminate the scene with cool moonlight and alternating warm orange and cyan lamps along the walls; use shadows, reflections/material roughness, and atmospheric fog for a moody but colorful low-poly look.

Enemies are cartoon mutant trash gremlins that emerge from the dumpsters on either side. Prefer a cute animated alien/monster model, scaled around human-small size, with a simple green fallback blob mutant if the model is unavailable. Spawn one enemy periodically at a random dumpster location. Initially it slides sideways out from the dumpster (pop state), then chases the player through the alley. Give it a slight bob/wobble while moving and have it rotate toward the player. Enemies have one hit point. Aim with a centered white crosshair with cyan glow and click or press Space to fire a short bright cyan laser tracer from the camera; raycast against the closest enemy under the crosshair and remove it on a hit. Play a laser sound on firing and a light impact sound on a successful hit if audio is available. Use a brief firing cooldown of about 0.18 seconds so shooting is rapid but not continuous.

The objective is to survive and eliminate mutants before they reach the player. Start with Score 0, Lives 3, and Wave 1. Each defeated enemy awards 10 points. Every 80 points, increase the wave by one and reduce the spawn interval, down to a minimum of about 0.55 seconds, so the action gets faster. Enemies move toward the player at roughly 1.15 + wave*0.11 speed. When an enemy comes within about 1.05 units, remove it and reduce lives by one; give the player about 1.1 seconds of hit invulnerability. At zero lives, stop the run, mark game over, show the retry overlay, and allow restarting with the state reset.

Overlay a responsive HUD on the screen: a bold yellow “Dumpster Panic” title at top left, dark translucent rounded pills at top right displaying Score, Lives, and Wave, and a centered crosshair. Show a dark translucent rounded message bar near the bottom with contextual text such as the initial controls message, “They pop out of the dumpsters — keep backing up and shoot the mutants,” hit/lives feedback, wave announcements, and game-over text. Before play, cover the view with a dark radial-gradient overlay and centered rounded card titled “Dumpster Panic” in large yellow display lettering. The card should explain that mutant trash gremlins jump from alley dumpsters and that the player must move, aim, and blast them; list desktop and phone controls; and include a large yellow-to-orange rounded “Start Alley Run” button with a darker pressed/shadow effect. Starting hides the overlay, resets score/lives/wave and player position, and requests mouse pointer lock. On game over, restore the overlay and change the button to “Retry Alley Run.” Keep the visual style all-ages, playful, moody, and clearly fictional; do not add real-world targets or unrelated mechanics.
