It's pretty much a standard Kirby game. Everything about the game just screams plain cute and charming, but gameplay itself manages to be actually quite hard. There isn't much too much unfairness in my opinion, levels and bosses can be willed through with sheer perseverance and they have their patterns that aren't too difficult to master.

It wasn't until the end until the game started to show it's cracks. The levels felt like going on and on with difficult spots and while the last world has some shorter levels, they still manage to ruin them with trial-and-error-autoscroller segments. Still, King Dedede returned back to normal formula and managed to be fair boss, though on the tougher side.

The colorization hack itself does a great job bringing this game to GBC. It even runs well on the original hardware with a flash cart. (I've learned this isn't a given with all GB hacks.)
