CULT OF THE VOID

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 responsive browser idle/clicker game titled “CULT OF THE VOID,” with a dark black-metal occult aesthetic. The game is a single-page interface, optimized for desktop and mobile. Use a near-black background with subtle burgundy radial glow, deep plum panels, crimson borders and highlights, pale bone text, muted gray-pink secondary text, and occasional gold controls for special actions. Use Georgia/serif typography, heavy letter spacing, uppercase labels, and restrained red glow effects.

Layout: At the top, add a header showing “CULT OF THE VOID” and the subtitle “BLACK METAL IDLE // THE ALTAR HUNGERS,” plus SAVE and RESET buttons. Beneath it, show four compact stat boxes: SOULS, SOULS / SEC, VOID MULTIPLIER, and DARK ESSENCE. The main area is a two-column layout on wider screens and stacks vertically on narrow/mobile screens. The left panel is titled “THE CURSED ALTAR” and contains a square clickable canvas altar; the right panel is a tabbed management panel with CULT, RITUALS, and OMENS tabs. Add a small footer note stating that progress saves automatically, offline harvest is calculated on return, and purchases are optional and never required.

The central altar should visually match the supplied screenshot: a nearly black canvas with a large dark plum oval/round occult structure centered in it, outlined in layered crimson-red rings. Inside is a smaller red-rimmed oval with a black center and a bright red skull glyph. Radial red spokes divide the outer oval into ritual segments. At the bottom, draw a trapezoidal altar pedestal with a red outline and the words “OFFER SOULS” in pale serif lettering. The outer shape should subtly pulse, the spokes should very slowly rotate, and clicking/tapping anywhere on the altar should produce a brief screen shake, red particle burst, and floating “+N” soul text. Include the persistent bottom hint “TAP THE ALTAR TO OFFER A SOUL” with a gentle pulsing opacity animation.

Core mechanic: this is an incremental soul-production game. Every altar click grants click power, increments a click counter, and adds the gain both to current SOULS and lifetime/run TOTAL SOULS. Base click power is 1. Iron Sigil upgrades add +2 click power per level; Sacrificial Geometry upgrades multiply click power by 2 per level. The overall multiplier begins at x1 and is increased by Dark Essence at +3% per essence, Endless Chant at x1.25 per level, and Ritual Automation at x1.5 per level. Display formatted large values with compact units such as K, M, B, T, Qa, and Qi.

Generators are purchased with current Souls and automatically generate souls every second. Show them in the CULT tab as cards with icon, name, owned count, description, production per second, escalating cost, and a SUMMON button. Costs scale by floor(base cost × 1.16^owned). The five generators, in order, are: Ashen Acolyte (icon ☿, “Whispers into the void.”, base cost 15, +0.6 SPS each); Blood Sister (✟, “Bleeds devotion into the sigils.”, base 110, +4 SPS); Grave Knight (♜, “Harvests souls from forgotten tombs.”, base 900, +22 SPS); Void Beast (☠, “A hunger given claws.”, base 8000, +130 SPS); Abyssal Avatar (♛, “The cult made flesh. The end begins.”, base 75000, +800 SPS). The first is available immediately; subsequent generators unlock based on lifetime/run total Souls at 50, 1,000, 10,000, and 100,000 respectively. Locked cards are dimmed and explain their unlock threshold. The Cult tab should also show a “Next Unlock” progress card with a red meter and a gold DAILY button. Once per calendar day, DAILY grants 100 Souls plus 50 per ascension.

The RITUALS tab should list these capped upgrades as cards with level, description, escalating cost using floor(base × 2.2^level), and a RITUAL button: Iron Sigil (base 30, max 20, “Click power +2.”); Endless Chant (base 250, max 10, “All production x1.25.”); Sacrificial Geometry (base 1500, max 6, “Click power x2.”); Ritual Automation (base 12000, max 5, “All generators x1.5.”). Include a visually consistent informational card labeled “Monetization-ready” explaining that cosmetic skins, rewarded ads, and premium boosts could be added later, but progress never depends on them; its PREVIEW button should simply show a toast that the Void accepts no shortcuts.

Add an Ascension card in the CULT tab. Ascension resets current Souls, total Souls, clicks, all generators, and all upgrades, while preserving Dark Essence and ascension count. The first requirement is 1,000,000 total Souls and each next requirement is multiplied by 5. Grant floor(sqrt(totalSouls / 1,000,000)) Dark Essence, with a minimum of 1, then show a gold ASCEND button and a celebratory gold particle burst. Dark Essence permanently contributes the +3% multiplier bonus. Show the current bonus percentage and requirement on the card.

The OMENS tab should contain a “Quest: First Century” card requiring 100 altar clicks; after completion, a CLAIM button grants 500 Souls once. Also list milestone achievements with locked/unlocked styling: First Offering (at least 1 click), A Hundred Whispers (at least 100 clicks), Cult of Ten (at least 10 total generators owned), Soul Millionaire (at least 1,000,000 total Souls), and Beyond Death (at least 1 ascension). Unlocked achievements should show a bright symbol and “UNLOCKED”; locked ones should be dim and say “Keep feeding the void.”

Implement persistence with local storage under a game-specific save key. Provide explicit SAVE and RESET controls, automatic periodic saving, and save on page exit. On returning after being away, calculate offline generator production for elapsed time capped at three days; only show an offline harvest message when the elapsed time exceeds eight seconds, reporting Souls gained and minutes away. Add brief crimson toast notifications for purchases, failed purchases, daily rewards, quest rewards, and ascension. Keep all purchases optional and do not introduce combat, enemies, movement, maps, or features beyond this altar-clicking and idle-management loop.
