I played the demo at gamescom. Controls feel great, the art style is even better live than in the videos, and the 2 player coop mode makes the game predestined for playing with casual gamers and kids. Definite buy for me now.
The demo was pretty short, only three levels, I think it was the same as E3. Being able to transform at will is cool, though I must say I never played any other Kirby games before and didn't have any reservations about that. You can transform into the parachute or a stone while jumping (so its just a substitute for abilities like gliding or buttstomp), auto transform into a submarine in water, and transform into a car to speed up. The only other transformation in the demo was the tank, I think. I played the blue king and steered the tank as well as threw missiles, while the Kirby player punched with a giant glove.
The levels were also on the easy side, nothing very challenging. The dragon bossfight was fun in spite of that. We have to wait if later levels get challenging enough. But as I said, definite buy either way.
