Added a tutorial system

I updated the tutorial so it works better, and has a progress based system

I added an interactive tutorial. I also created documentation for the scripting.

Particle Simulation: Real-time 2D particle engine with gravity, collisions, and velocity.
Type System: Group particles into types, each with customizable properties (color, elasticity, gravity scale, blob eligibility, etc.).
Per-Type Gravity: Each type can have its own gravity scaling factor, allowing for diverse behaviors.
Lasso Selection: Draw a lasso to select multiple particles; persistent highlight until cleared or type is created.
Type Creation & Assignment: Create new types from selected particles, assign selection to existing types, rename, recolor, and delete types.
Panel UI: Multiple draggable, collapsible panels (Control, Types/Selection, Zoom/Stats, Custom Behavior) for organized controls.
Custom Behavior Scripting: Write custom JavaScript to control particle behavior each frame, with support for execution phases and unsafe mode.
Code Editor with IntelliSense: Integrated CodeMirror editor for scripting, with syntax highlighting, autocomplete, maximize/minimize, minify, and run-once features.
Pause/Resume & Safety: Simulation can be paused/resumed; pause button is disabled during selection to prevent conflicts.
Range Input & UI Polish: Consistent, modern styling for sliders and controls.
Zoom & Stats Panel: View zoomed-in region of the simulation and real-time stats (particle count, density, average speed, color).
Blob Rendering: Optional blob visualization for eligible types, with adjustable density and radius.
Advanced Scripting Directives: Use @phase and @unsafe directives in scripts to control execution timing and access.
Persistent Highlighting: Selected particles remain highlighted until cleared.
Grid Visualizer: Toggleable grid overlay for spatial debugging.
Velocity Coloring: Option to color particles based on their velocity.
Preset System: Quickly switch between different simulation presets (e.g., Light Spray, Dense Fluid, Lava Pool).
Force Tools: Apply forces to particles with adjustable strength and radius.
Auto Capacity Estimation: Automatically estimate the maximum stable particle count for 60 FPS.
Responsive Layout: Panels and canvas adapt to window resizing and support drag repositioning.

I like to commit all at once so this might be long. Geo gameplay

Leaflet world map + optional Google Street View (auto-fallback to photo).
Random location generator (bias to provided places.json; global random fallback).
Click-to-guess flow, haversine-based scoring with exponential decay.
Per-round results (actual vs. guess line), match length selector, per‑round timer.
Winner modal at match end; Reset/Next controls; WASD move + Q/E zoom in Street View.
Pano popout/expand/dock and draggable popout; responsive map/pano resizing.
Multiplayer

Room create/join/leave, player names, live scoreboard/leaderboard.
Host-authoritative scoring and timing; auto-advance when all guessed or on timeout.
Active host sync of round, scene, settings, endsAt timer, and roster names.
Dual transport: WebRTC data channels with WebSocket signaling + BroadcastChannel fallback.
Message de-duplication (IDs), graceful error handling (try/catch/onerror).
Advanced tab auto-enabled only when signaling server is reachable; host restart sync.
Desktop UI/UX

Window manager (minimize/maximize/close), dock with bounce, app switcher (Ctrl+Tab).
Spotlight search (Ctrl+Space) across apps and files; desktop icons with drag/snap.
Smooth open/minimize/close animations with reduced‑motion support.
Global UI scale setting; maximize keeps game canvases correct; game windows no-scroll.
App hero/banner images; consistent iconography; new intro popup (SweetAlert) with “Don’t show again.”
Favicon included.
Built-in apps (selection)

Tools: Files, Editor, Terminal, Markdown, Kanban, Converter, Pomodoro, Recorder, Palette, Pixel Art, PDF Viewer, World Clock, Settings.
Games: Memory, 2048, Snake, Minesweeper, Tic‑Tac‑Toe, Calendar, Gomoku, 15‑Puzzle, Mastermind, Invaders, Asteroids, Flappy, Pong, Breakout, Tetris, Othello, Hangman, Simon, Blackjack, Checkers, Connect 4, Wordle, Sudoku.
Media/Utility: Camera, Gallery, CSV/JSON viewers, Text Diff, Cipher, FS Tree, Music Player.
Paint: Vector editor + raster paint (brush/eraser, thickness, color, undo/redo, clear, PNG save).
Tech & posture

Vite-based build; Leaflet + Google Maps JS (Street View optional).
Server signaling via WebSocket; client guards and fallbacks.
places.json support to seed locations; local virtual FS for files.

I added a rule book!

I made the whole game.

I created the grid, implemented movement. I also added drawing selection, shortcuts, etc
