+# Zelda Dungeon
+
+A top-down, Legend of Zelda-style dungeon crawler with procedurally generated dungeons. Browser-first (plain Canvas + JS), with an optional Electron wrapper.
+
+> Personal prototype project — functional, but not polished.
+
+## Features
+
+- Procedural dungeon generation (seeded, reproducible) with 100 dungeon definitions
+- Room-based exploration with locked doors, keys, levers, and push-block puzzles
+- 22 enemy types with distinct stats and AI behaviors
+- 12 weapons with different damage, range, and effects
+- Boss encounter per dungeon
+- Items: potions, heart pieces, arrows, bombs
+- Dungeon themes (Forest, Desert, Mountain, and more)
+- Save system (Electron build)
+- Runs in any modern browser — no build step required
