Cosmos Forge

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-based sci-fi incremental/clicker game titled “Cosmos Forge,” subtitled “From a single cell to multiverse dominion.” The player progresses from a single cell to Multiverse Dominion by clicking an evolution button, buying automated producers, researching upgrades, converting resources, unlocking eras and achievements, and eventually collapsing universes for permanent prestige power.

Use a dark, atmospheric cosmic presentation. Render an animated full-screen canvas starfield behind the interface: hundreds of twinkling blue, purple, cyan, and occasional warm stars, a soft central radial nebula/core, and thin animated orbital rings. The visual intensity and palette should evolve with progress: early stages are blue/cyan; Stellar Collision adds orange/red warmth; galaxy stages add cold cyan/blue arcs; universe stages add pale violet; multiverse stages add hot magenta, gold, and purple. Keep the UI above the background with a translucent navy/black overlay, rounded glassy cards, subtle borders, blur, shadows, and luminous gradients. Use large bold white headings and pale blue secondary text. The layout should be responsive: desktop uses a three-column main grid and mobile collapses to one column.

At the top show the large title and subtitle, plus “Mute: Off/On” and a red/pink “Reset Save” button. Below, show a horizontal era progression bar with active highlighted nodes and thresholds. The eleven eras and lifetime Matter thresholds are: Single Cell (0), Multicellular (50), Toolmakers (300), Industry (1,500), Spacefaring (6,000), Colonization (20,000), Quantum Mastery (75,000), Stellar Collision (150,000), Galactic Expansion (250,000), Universe Forging (1,000,000), and Multiverse Dominion (5,000,000). The current era is based on total lifetime Matter; display the era’s descriptive text, beginning with “You are a single cell pushing against the void.”

Under the era bar show three resource cards: Matter, Antimatter, and Dark Matter, each with its current formatted amount and an automatic +amount/s rate. Matter is the primary resource. Start with all resources at zero, click power 1, no producers, no upgrades, and no prestige shards. Format large values with K, M, B, T, Qa, Qi, and Sx abbreviations.

The main left panel is “Origin Pulse.” Show current era flavor text, a large glowing circular/radial-gradient button labeled “Evolve,” click power, and “Lifetime Matter.” Each click grants effective click power Matter and adds it to lifetime Matter. The Evolve button should visually change at late eras: blue/cyan early, violet in Universe Forging, and gold/magenta in Multiverse Dominion. Add conversion controls: “Convert 100 Matter → 1 Antimatter,” enabled once the player has 100 Matter; and, once Colonization is reached, “Convert 50 Antimatter → 1 Dark Matter,” enabled with enough Antimatter. Conversion consumes the input and adds the output, with upgrade and achievement multipliers affecting gains.

Also place a “Universe Collapse” prestige panel in the Origin Pulse area. It explains that a mature universe can be collapsed for permanent Singularity Shards, displays shard count, collapse count, and the permanent bonus (each shard gives +12% production and click power). The Collapse Universe button is disabled until Universe Forging is reached and at least one Universe Engine is owned. When used, ask for confirmation, reset normal resources, producers, upgrades, achievements, and temporary multipliers while retaining prestige shards, collapse count, mute setting, selected realm tab, and buy mode. Reward is at least 1 shard and scales from Universe Engines, Multiverse Looms, and lifetime Dark Matter.

The center/right “Growth Chain” panel contains x1, x10, x100, and Max bulk purchase buttons, with the selected mode highlighted. Show unlocked producer cards; producers become visible when lifetime Matter reaches their unlock threshold, and remain visible once owned. Every card has name, owned count, description, bulk cost in Matter, output per unit, and a purchase button. Producers and exact values are:
- Cell Cluster: base cost 15, cost growth 1.16, +0.4 Matter/s, unlock 0; description “A small colony of cooperating cells.”
- Tissue Web: base 60, growth 1.18, +1.8 Matter/s, unlock 40; “Specialized structures strengthen growth.”
- Toolsmiths: base 240, growth 1.20, +6 Matter/s, unlock 220; “Basic tools amplify output.”
- Factories: base 900, growth 1.22, +20 Matter/s, unlock 1,000; “Automated industry floods the system with matter.”
- Orbital Foundry: base 4,200, growth 1.24, +68 Matter/s and +0.14 Antimatter/s, unlock 4,500; “Manufacturing now happens in orbit.”
- Colony Ark: base 15,000, growth 1.26, +180 Matter/s and +0.55 Antimatter/s, unlock 13,000; “Whole planets become productive nodes.”
- Quantum Lattice: base 80,000, growth 1.28, +550 Matter/s, +3.4 Antimatter/s, +0.08 Dark Matter/s, unlock 55,000; “Exotic computation bends physics into profit.”
- Galaxy Forge: base 300,000, growth 1.30, +1,800 Matter/s, +14 Antimatter/s, +0.45 Dark Matter/s, unlock 220,000; “Star systems are coordinated into galaxy-scale output networks.”
- Universe Engine: base 1,500,000, growth 1.32, +6,200 Matter/s, +52 Antimatter/s, +1.8 Dark Matter/s, unlock 900,000, and requires 500 Galaxy Forges; “Fresh universes are spun up as industrial assets.”
- Multiverse Loom: base 9,000,000, growth 1.34, +24,000 Matter/s, +220 Antimatter/s, +7.5 Dark Matter/s, unlock 4,500,000, and requires 25 Universe Engines; “Parallel realities are woven together for impossible yields.”

Producer costs should scale as floor(base cost × growth^owned), and bulk purchases should buy as many as affordable for x1/x10/x100 or up to 1,000 for Max. Automated production runs continuously and contributes to lifetime totals. Cell Cluster and Tissue Web production are affected by the cell multiplier; Factories and Orbital Foundries by the industry multiplier; all production is affected by global, achievement, and prestige multipliers.

Add a “Cosmic Realms” panel with Galaxy, Universe, and Multiverse tabs. Galaxy is initially available; Universe unlocks at Universe Forging or with a Universe Engine; Multiverse unlocks at Multiverse Dominion, with a Multiverse Loom, or after a collapse. Galaxy content explains Galaxy Forge ownership and the 500-forge Universe Engine requirement, plus a “Visual Shift” message. Include the Dark Giant condensation mechanic in the Galaxy realm: once at least 100 Galaxy Forges are owned, a button “Forge 1 Dark Giant from 100 Galaxies” consumes 100 Galaxy Forges and creates one Cosmic Dark Giant. Each Dark Giant produces 25,000 Matter/s, 260 Antimatter/s, and 12 Dark Matter/s, multiplied by global/prestige bonuses and a Dark Giant multiplier. Include a dark purple special card and support the Dark Giant Heart and Abyssal Halo upgrades. Universe content shows Universe Engines, whether the 500-Galaxy requirement is met, and current collapse potential. Multiverse content shows Multiverse Looms, Singularity Shards, collapse count, and prestige percentage.

Add an “Upgrades” panel. Unpurchased upgrades appear after their lifetime Matter unlock threshold and required Dark Giants are met. Purchases consume listed resources and apply permanently for the current run:
Reactive Membrane: cost 25 Matter, unlock 10, +1 click power.
Stable Nucleus: 120 Matter, unlock 60, doubles cell-based production.
Dexterous Hands: 360 Matter, unlock 260, +3 click power.
Assembly Theory: 1,800 Matter, unlock 1,200, doubles industry production.
Antimatter Containment: 6,500 Matter and 10 Antimatter, unlock 5,000, doubles manual Matter-to-Antimatter conversion.
Void Lens: 120 Antimatter and 3 Dark Matter, unlock 30,000, doubles Dark Matter conversion.
Entanglement Mesh: 50,000 Matter, 400 Antimatter, 20 Dark Matter, unlock 65,000, multiplies all production by 1.5.
Galaxy Core Stabilizers: 260,000 Matter, 1,200 Antimatter, 40 Dark Matter, unlock 230,000, multiplies Galaxy Forge and Universe Engine output by 1.35 (or implement the shown global production effect consistently).
Cosmic Blueprint: 1,200,000 Matter, 6,500 Antimatter, 120 Dark Matter, unlock 950,000, +12 click power.
Many-Worlds Tuning: 5,000,000 Matter, 18,000 Antimatter, 500 Dark Matter, unlock 4,200,000, doubles all production.
Dark Giant Heart: 3,500,000 Matter, 12,000 Antimatter, 420 Dark Matter, unlock 1,200,000, requires 1 Dark Giant, doubles Dark Giant output.
Abyssal Halo: 12,000,000 Matter, 55,000 Antimatter, 1,800 Dark Matter, unlock 5,000,000, requires 3 Dark Giants, multiplies all production by 1.5.

Add an “Achievements” panel listing all achievements, with locked muted cards and unlocked cards highlighted gold. Unlock checks and rewards are: First Spark at 10 Matter or lifetime Matter, +15% click power; Budding Life for 5 Cell Clusters, +10% automatic Matter; Tool Time at Toolmakers, +20% click power; Industrial Dawn for 3 Factories, +15% automatic production; One Small Step for 1 Orbital Foundry, +10% Antimatter; Antimatter Age at 25 Antimatter or lifetime Antimatter, +10% automatic production; Into the Void at 10 Dark Matter or lifetime Dark Matter, +15% Dark Matter; Quantum Crown for 2 Quantum Lattices, +25% automatic production and +10% click; Galactic Reach for 1 Galaxy Forge, +20% automatic production; Universe Architect for 1 Universe Engine, +25% Antimatter and Dark Matter; Multiverse Throne for 1 Multiverse Loom, +35% automatic production and +15% click.

Use toast notifications for era unlocks, achievements, conversions, purchases, upgrades, forging Dark Giants, and universe collapse. Play simple synthesized UI tones for clicks, purchases, unlocks, achievements, and collapse, with the mute toggle disabling sound. Persist the game in localStorage under a save key, autosave periodically, save before unload, and provide Reset Save with confirmation. Keyboard shortcuts: M toggles mute, R opens reset behavior, P attempts prestige, and number keys 1/2/3/4 select x1/x10/x100/Max buying. There is no hard ending: the goal is to reach and continue progressing through Multiverse Dominion while accumulating prestige power across collapsed realities.
