How it works
The world is a toroidal 2D grid of terrain tiles, not discrete rooms. Players see a viewport centered on their position. Terrain types have mechanics — shallow water slows you, mountains block you, forests hide you.
Combat is timing-based with telegraphed moves and cooldown management, not turn-based.
The server runs a tick-based async game loop alongside the telnet server. SQLite handles persistence. Session mode stacks filter what reaches the player depending on context (exploring, fighting, composing, solving puzzles).
