Verdant Abyss

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 browser-playable first-person 3D survival game titled “Verdant Abyss,” set on a tropical rainforest island surrounded by a large alien ocean. Use a colorful low-poly/toon aesthetic: bright sky-blue background, blue fog, vivid green island terrain with sandy shoreline bands, chunky stylized trees and rocks, and a translucent deep-blue ocean extending far beyond the island. Underwater, add a dark teal seabed at depth, colored glowing alien coral clusters, and scattered underwater fish/salvage pickups. Use a first-person perspective with the player camera at head height, a small white crosshair centered on screen, mouse pointer-lock/right touch-pad look, and WASD movement. Support Space to jump on land or swim upward, Shift to sprint on land or dive downward underwater, Ctrl/X to crouch, E to collect or interact, C for crafting, I for inventory, number keys 1–4 for quick-use slots, and mobile controls consisting of a lower-left virtual joystick, a right look pad, and visible Jump, Dive, Use, Craft, and Pack buttons.

The playable loop is exploration and resource survival. Start the player near the island shore with health 100, hunger about 84, thirst about 78, oxygen 100, stamina 100, infection 0, poison 0, one water item, and empty resource/crafted-item counts. Scatter collectible low-poly pickups across land: wood, green vines, gray stone, bright plants, plus salvage near washed-up crates/barrels. Scatter fish and salvage underwater. Press E or mobile Use near a pickup to collect it; pickups rotate and disappear when collected. Some plant pickups can trigger poisonous sap, raising poison. Include three glowing cyan research beacons (two on the island and one farther out beyond/near the reef); interacting with each increments a “Beacons X/3” objective and turns its orb white. Populate the island with stylized tree and rock models, and include hostile wildlife: a land crab and alien predator that approach when nearby on land, plus aquatic fish/blob-fish predators that pursue the player underwater. Wildlife bites reduce health and raise infection; a crafted spear can repel nearby predators when quick-used.

Implement survival meters continuously draining: hunger and thirst decline over time, oxygen declines rapidly while submerged and refills at the surface, stamina drains while sprinting and regenerates otherwise. Hunger/thirst at zero damage health; oxygen depletion causes drowning damage; poison causes ongoing damage and gradually contributes to infection; high untreated infection causes damage. Death can result from wildlife, drowning, starvation, dehydration, poison/infection, and should show a death overlay with the reason and a Restart button. The water should visually become more opaque/darker with denser teal fog while swimming.

Add a Craft and Pack/Inventory interface. Craft recipes must match these materials and purposes: axe (2 wood, 1 stone, 1 vines; gathers wood faster), spear (2 wood, 1 stone, 1 vines; defense), fire (3 wood, 2 stone; cooks fish and purifies water), shelter (5 wood, 3 vines; slows hunger/thirst drain nearby), fins (4 vines, 2 salvage; faster swimming), oxygen tank (5 salvage, 2 vines; doubles oxygen duration), base (6 wood, 4 salvage; places a small floating base module), antidote (5 plants, 1 fish, 1 salvage; cures infection and poison), and transmitter (8 salvage, 2 stone, 2 vines; enables extraction after all beacons). Crafted fire, palm shelter, and floating base should visibly place simple low-poly structures in front of the player: a ring and orange flame, a four-post palm-like shelter with roof, and a square floating deck with a flag. Fire can gradually convert fish into cooked fish. The quick bar should contain four slots: water, cookedFish, antidote, and spear. Number keys/use actions consume water to restore thirst, cooked fish to restore hunger, antidote to sharply reduce infection and clear poison, or thrust the spear if crafted.

Place a persistent HUD over the 3D view. At the top, show the large mint-green title “VERDANT ABYSS” and a dark translucent rounded objective panel reading initially “Beacons 0/3 • Craft antidote + transmitter • Survive hunger, thirst, oxygen, poison, infection.” At the lower left show labeled horizontal bars and numeric values for health (red), hunger (yellow), thirst (blue), oxygen (pale cyan), stamina (mint), infection (purple), and poison (green). At the bottom center show four outlined quick slots labeled 1 water, 2 cookedFish, 3 antidote, 4 spear, with counts. On mobile/portrait layouts, use large rounded light-blue and mint buttons for Pack, Craft, Dive, Jump, and Use, with translucent dark panels behind the controls; retain the centered crosshair. Craft opens a panel listing every recipe, costs, description, and Craft buttons; Pack opens inventory counts and crafted items.

After all three beacons are scanned and both an antidote and transmitter have been crafted, change the objective to “Extraction ready: reach the cyan beam beyond the reef.” Spawn a tall translucent cyan extraction beam at approximately (95, 22, 72), beyond the reef, and complete the game when the player reaches within about 7 units of its ground location, displaying a success message such as “Extraction reached. You survived Verdant Abyss!” Keep the overall presentation bright, stylized, low-poly, and readable, with smooth shadows, simple ambient/directional lighting, and clear feedback messages such as collected resources, beacon scans, crafting, poison, predator bites, and survival victory.
