Although I have only played 2 Kirby games, I would highly recommend Kirby Canvas Curse. It is still one of my favorite games on the DS. It perfectly uses the the touchscreen controls and has one of the best final boss fights out there.
Currently Playing: Mario Kart 7, Mario Kart 8, Luigi's Mansion: Dark Moon, The Legend of Zelda: Majora's Mask, Super Smash Bros for Wii U
Predictions:
Super Mario Galaxy will pass Super Mario 64 in total sales CORRECT!
