+# Heros Web Roadmap
+
+## Initial Goal
+
+Build a small complete tactical RPG loop:
+
+1. Title screen
+2. Prologue story
+3. First battle briefing
+4. First battle
+5. Battle result and save point
+
+## Current Slice
+
+- Vite, TypeScript, and Phaser project foundation
+- Title scene with a new game entry point
+- Prologue dialogue scene backed by scenario data
+- First battle scene with a 12x12 map, terrain colors, unit placement, and movement range preview
+- Flow verification script from title to first battle
+
+## Next Steps
+
+1. Add selectable commands: move, attack, wait
+2. Implement grid movement and occupied-tile blocking
+3. Implement attack range, damage, defeat, and victory checks
+4. Add a simple enemy AI turn
+5. Add battle result scene and local save/load
+
+## Content Direction
+
+- Use original names, portraits, maps, and dialogue inspired by historical tactical RPGs.
+- Keep copyrighted scripts, sprites, portraits, music, and maps out of the repository.
+- Prefer data-driven scenarios so new chapters and battlefields can be added without rewriting scene code.
