Deep and layered castle management with many customization options, including monster recruitment, training, traps, and castle layout.

The UI can become cluttered and difficult to navigate in late game, with no search or sorting functions for monsters and items.
Gameplay involves frequent repetitive pop-ups and dialogs that interrupt flow, lacking an auto-skip feature.
Some players find the pace slow or grindy and controls clunky on PC, as the game is more suited for mobile touch controls.
