It's a cute idea to tilt entire Game Boy Color™ to move your little Kirby on small screen. Honestly, level design is a delight, game gives you a ton of lives (since you are going to lose about the same amount), obstacles interesting to overcome, secrets are really cute, minigames are fun. It's a genuinely good cute Kirby game.
But holy shit, controlling it with undocked Nintendo Switch™ is a nightmare. I was genuinely concerned if I ether will smack my head over Switch screen or accidentally undock my Joycons and drop console into pieces. I probably should have played this with unattached Joycon to save myself some nerves but what's done is done. Ether way, game sometimes requires you to be way too precise, especially for some secrets. Don't get me wrong, I'm all for this kind of re-releases, its a unique game and it must be preserved to experience.
