Anyone has something to say about Kirby and the Rainbow Curse ?
It looks to be a unique game and the reviews and opinions looks to be mixed about it.

I have it and I quite liked it, but it's not for everyone. It took me a while to get accustomed to the stylus controls.

On topic: Fire Emblem Fates Revelations. I think this is download-only.
