+# React + TypeScript + Vite
+
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) for Fast Refresh
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
+
+## React Compiler
+
+The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+
+```js
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+
+      // Remove tseslint.configs.recommended and replace with this
+      tseslint.configs.recommendedTypeChecked,
+      // Alternatively, use this for stricter rules
+      tseslint.configs.strictTypeChecked,
+      // Optionally, add this for stylistic rules
+      tseslint.configs.stylisticTypeChecked,
+
+      // Other configs...
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
+```
+
+You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
+
+```js
+// eslint.config.js
+import reactX from 'eslint-plugin-react-x'
+import reactDom from 'eslint-plugin-react-dom'
+
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+      // Enable lint rules for React
+      reactX.configs['recommended-typescript'],
+      // Enable lint rules for React DOM
+      reactDom.configs.recommended,
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
+```

+
+### Project: The Void Chamber
+A whimsical pocket dimension where digital companions called "Voidlings" float around and react to your presence.
 
 ### Current Progress
-- [ ] Project initialized with Vite + React + TypeScript + TailwindCSS
-- [ ] Basic project structure in place
-- [ ] First "Hello World" page running
+- [x] Project initialized with Vite + React + TypeScript + TailwindCSS
+- [x] Basic project structure in place
+- [x] First "Hello World" page running
+- [x] React Router added for navigation
+- [x] Main Chamber view created with floating voidlings
+- [x] Ability to name and rename voidlings
+- [x] localStorage persistence for voidlings
+- [x] Particle effects and ambient glows added
+- [x] Voidling types/classes with different behaviors
+- [x] Mood-specific animations
 
 ### In Progress
 (None yet)
 
 ### Completed
-(None yet)
+- Initialized Vite + React + TypeScript project
+- Added TailwindCSS configuration
+- Created "The Void Chamber" landing page with interactive voidlings
+- Added React Router for navigation between landing and Chamber pages
+- Created Chamber page with floating animated voidlings
+- Added ability to summon, name, rename, and release voidlings
+- Added localStorage persistence to remember voidlings between sessions
+- Added mood system (idle, happy, curious, sleepy) with click interaction
+- Added particle effects and ambient glows for atmosphere
+- Added 4 voidling types: Wisp (ethereal), Blob (bouncy), Spark (energetic), Ember (warm)
+- Added voidling behaviors: spark moves faster, sleepy slows down, happy gets energetic
+- Added mood-specific animations (bounce, pulse, ping)
+- Added feeding interaction
+- Added petting interaction (♡ button) - makes voidlings happy
+- Added achievements system with 10 unlockable achievements
+- Added user stats tracking (total pets, feedings, sessions)
+- Added night/day cycle with 4 time phases (dawn, day, dusk, night)
+- Added time-based visual themes with different gradients and ambient colors
+- Added automatic time progression (1 minute per full cycle)
+- Added manual time control toggle
+- Added voidling speed multipliers based on time of day (slower at night)
+- Voidlings naturally become sleepy at night
+- Added Void Essence currency - earned by petting (+2) and feeding (+3)
+- Added Void Shop with purchasable voidling eggs, treats, and items
+- Added 2 new voidling types: Glitch (rare green) and Crystal (rare blue)
+- Added "Void Tycoon" achievement for accumulating 500 Void Essence
+- Updated biodiversity achievement to require all 6 voidling types
+- Added sound effects system using Web Audio API (pet, feed, spawn, achievement, purchase, release)
+- Added mute toggle button to control sounds
+- Added Void Hunt minigame - click targets for 30 seconds to earn Void Essence
+- Added Star Catcher minigame - catch falling stars for higher rewards (10 Void Essence per star)
+- Added purchasable chamber decorations: Crystal Orb, Void Flame, Ancient Tome, Moon Stone
+- Decorations appear in the chamber with ambient pulsing animation
 
 ### Next Steps
-1. Initialize the project with Vite, React, TypeScript, and TailwindCSS
-2. Create basic app structure (routes, layout)
-3. Deploy a working "Hello World" page
-4. From there, iteratively add features based on chosen domain
+1. Add more minigames (DONE - added Star Catcher)
+2. Add voidling evolution/combat system
+3. Add more chamber decorations/ways to customize chamber
+4. Add achievement for catching stars in Star Catcher
