This project is a polished, browser-based Catan adaptation built in a single index.html file (no build step required).

Recent improvements focused on reliability and smooth gameplay:

• Auto-save system
  • The game now auto-saves every 30 seconds during active play.
  • A final silent save is attempted on tab close / refresh.
• Better keyboard controls
  • R = Roll dice
  • E = End turn
  • 1 = Open build menu
  • 2 = Open trade menu
  • 3 = Open development card menu
  • 4 = Buy development card
  • M = Toggle music on/off
  • Ctrl/Cmd + S = Save game now
  • Esc = Cancel current placement/action
• Safer game lifecycle handling
  • Auto-save starts on new game and loaded games.
  • Auto-save is stopped when quitting the game.
  • Manual save still exists for explicit snapshots.

1. Clone the repository.
2. Open index.html in any modern desktop browser (Chrome, Edge, Firefox, Safari).
