To me, Nightmare is the definitive Gameboy Kirby experience. Although Super Star has ideas that far surpass Nightmare, the refined mechanics and flashiness of Nightmare make up the difference and then some. Though I found this game a little frustrating to 100%, the experience was certainly worth it. I found the game delightfully straight-forward with HAL really getting in the groove for their addition of mini-games within the main game. Also delivers some of my favourite art and areas in the series, the Fountain of Dreams is iconic for a reason.
