The level design is like a cute adventure that's "sweet at first, then bitter"! The first few levels let you easily experience the joy of elimination, but from a certain level onwards, the difficulty suddenly "surges," from simple matching to elimination requiring strategic planning. Beginners can quickly get the hang of it, but passing the level requires some thought. Moreover, the arrangement of elements is different each time you play, there's no fixed pattern, it all depends on your on-the-spot reaction. Collecting the little pig badges after completing a level is super satisfying, making you want to "try another level to prove yourself."
