Doodle Harmony Idle Merge

Doodle Harmony Idle Merge combines idle progression with puzzle-like merging mechanics, where you combine elements to unlock new doodles and advance through whimsical levels. The game progresses passively while you're away, letting you return to discover growth and new content to merge. It's ideal for players who enjoy low-pressure progression loops and the satisfying click of combining items to see what emerges next.
