Symbiosis - Ecosystem Puzzle Game

Now I have a good understanding of the arcade. Let me brainstorm a unique game idea. Looking at the existing games, I notice there's no light reflection/laser puzzle game, no constellation/star connecting game (wait, there's constellation-cartographer), and no flocking/boids game (wait, there's murmuration). Let me think of something truly novel...

I'll create "Prism Path" — wait, there's already "prism" and "photon-path". Let me check what genres are missing:

• No sokoban-style box pusher? There's "box-pusher"
• No pipe connection game? There's "transit-link" and "neon-flow"
• No word typing game? There's "type-storm" and "word-forge" and "word-hunt"
• No color mixing game? There's "color-clash" and "chroma-shift"
• No rhythm game? There's "beat-drop" and "pulse"
• No tower defense? There's "nexus-defense" and "realm-guard"
• No idle/incremental game? There's "stock-tycoon"
• No farming/garden game? There's "bonsai-zen" and "biome-builder" and "terraform"
• No fishing game? There's "reef-keeper" and "tide-pool"
• No archery/aiming game? There's "gravity-golf" and "lunar-lander"
• No swarm/infection game? There's "hive" and "mycelium"
• No lockpicking game? There's "safecracker"
• No chemistry game? There's "powder-lab" and "alchemy-lab" and "vial-sort"
• No music/sequencer game? There's "harmony-grid" and "harmonograph"

I'll create "Symbiosis" — a unique ecosystem simulation puzzle game where you place different organisms on a grid and they interact with each other through food chain relationships. Each organism has specific needs (sunlight, water, prey) and produces resources for others. The goal is to create a self-sustaining ecosystem that survives for N turns. This combines puzzle mechanics with simulation and is genuinely novel for this arcade.

Let me build it.

*****************************************************************************************************************************************************************************************************************************************ts.

The file is too large for a single write. Let me build it in parts.

Let me write the game using shell commands instead, breaking it into parts.

Now let me verify the file is complete and check for syntax errors:

********************************************************************************************************************at:

************************************************************************on:

Now let me validate the JavaScript syntax by extracting and checking it:

*********************************************************************************************************************************************************************************************************************************************************el:

The eval failed because init() is called at the end and it tries to access canvas. But I can see the logic issue clearly: resources start at 0, so all organisms starve on turn 1. I need to fix this by giving starting resources or making the first turn's production free. Let me fix the simulation to give a small starting resource pool:

Now let me also reconsider the simulation logic more carefully. The current logic has issues:

1. Needs are checked against current resources, then production is added, then needs are subtracted. But needs and consumption are both subtracted. This double-counts.
2. The consumes with from field means the organism eats another organism type — it shouldn't also consume from the resource pool in the same way.

Let me rethink and fix the simulation to be cleaner:

Now let me write a proper simulation test to verify the levels are solvable:

Levels 1 and 2 are solvable. Let me test the more complex levels:

**********************************************************************************************************************************re:

Everything checks out. Now let me update the master arcade index. I need to add the new game card:

The search text wasn't found exactly. Let me check the exact content around the end of the game cards:

I see — the arrow character is a special unicode character. Let me use a more specific search:

The whitespace might be different. Let me use a more targeted approach:

**********************************************************************************************************************************************************81:

******************************************************************************************ne:

***********************************************************************************************************************id:

All HTML tags are balanced. Now let me do a final review of the game file to make sure everything is correct:

************************************************************************************************************************************************************ns:

Those "potentially undefined" items are all from comments or string literals (like "Grass" in descriptions, "needs" in comments, "rgba" in CSS strings, etc.), not actual function calls. The game is solid.

Let me verify the game is accessible at the expected URL path:

The game is complete and deployed. Let me provide a summary of what was built.

🌿 Symbiosis — Ecosystem Puzzle Game

I've created a unique ecosystem simulation puzzle game that's unlike any other game in the arcade. Here's what makes it special:

🎮 Core Concept

Build a self-sustaining ecosystem by placing organisms on a grid. Each organism has needs (resources it consumes) and production (resources it creates). The challenge is creating a balanced food web where every organism can survive every turn.

🧬 8 Organism Types

🎯 6 Progressive Levels

1. First Sprout — Simple Algae + Moss loop
2. Green Chain — Add Grass for Biomass
3. Decomposer — Mushrooms recycle Biomass → Sun
4. Food Web — Introduce Rabbits (with obstacles)
5. Apex Predator — Foxes hunt Rabbits (more obstacles)
6. Pollinator — Full ecosystem with Bees & Ferns

✨ Features

• Turn-based simulation with resource economy (Sun ☀, Water 💧, Biomass 🧬)
• Predator-prey mechanics — animals must find prey within radius 3
• Starving organisms have a 25% death chance per turn they can't produce
• Visual feedback: glowing organisms on production, particle effects, predator-prey connection lines
• Auto-play mode for watching your ecosystem run automatically
• Level select menu with all levels accessible
• Star ratings based on resource surplus
• Web Audio API sound effects (synthesized tones, no external files)
• Full controls: mouse click to place, right-click to remove, touch support
• Responsive design with collapsible sidebar
• Nature-inspired aesthetic with deep greens, organic gradients, and emoji-based organisms

All 6 levels have been verified as solvable through simulation testing. The game is self-contained with zero external dependencies.
