There are kinda two lines of Kirby games. The "Dreamland" series, including 1 through 3 and Crystal Shards, where generally the graphics are soft and feature pastels, Kirby moves slower, the ally animals are featured and can combine with Kirby to modify abilities, you collect 30 star pieces to get a 1up, all the copy abilities are based on simple elements and minimalist concepts like "Fire" and "Spike", and there is often an artistically abstract and disturbing end boss. Then the "Adventure" series including Superstar, Amazing Mirror, and Squeak Squad, with their more "edgy" and sharp sprites, fast-paced actions and movement, the copy abilities are mostly based on archetypes in fiction and original designs such as Fighter, Mirror Mage, and Yo-Yo, and Kirby's only friends happen to be himself, the Helpers he spawns, and his enemies.
Despite this game having Dreamland in the title, it seems to veer more towards the Adventure style. The style of the playable characters and the set of abilities suggest Adventure, yet a lot of the enemies and the story parts remind me of Crystal Shards so I can't quite put my finger on it.
