Resources are key in this merge game, i like how merging items unlocks new castle areas and keeps progress satisfying and relaxing.
Starting with merging, click to combine identical items and create new tools, unlocking rooms and gameplay features, which is kinda weird anyway, with no timers or pressure, just chill.
Inside the game, you click to restore and decorate the ancient castle, which is kinda weird anyway, buttons for repairing halls, unlocking new rooms, and discovering hidden items, their purpose is to advance the story while relaxing.
Quick merges help progress faster, then i noticed focusing on repairing and unlocking new areas makes overall gameplay more smooth and enjoyable, especially as new resources appear with each merge.
Castle stuff, gamey merges, and hidden object chains are the main features, i found that focusing on merging and unlocking areas is the best way to keep progressing in this cozy, relaxing game.
