Phantom Citadel is an endless core-defense arcade game. You are the last guardian of a haunted fortress. Phantoms drift inward from every edge to devour the soul core. Drag along the lower sanctum to reposition your guardian; tap to fire barrier pulses toward that direction. Banish wraiths before they touch the core, build combos, and grab soul shards for bonus points. There is no final stage—only rising threat tiers driven by your score. Chase your personal best in portrait mode.
This is a casual game.
