- title screen (continue/new/load/settings/help) and Esc pause menu - settings: language & sound, camera, graphics, game, rebindable keys; stored in localStorage and in every savegame (always applied on load) - savegames as JSON (.dcsave): download, load via file picker or drag & drop - autosave to localStorage every 2 minutes and when the tab is hidden/closed - configurable wall detail, light count, interface size, game speed, hints - audio behind a cargo feature so native tests run (cargo test --no-default-features) - savegame round-trip test Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
