This is a very early DS homebrew puzzle game, but well, it's still one of my favourites today.
You spell words out of the falling blocks, it's as simple as that.
It's got colourful graphics and some nice chiptune music, it's a shame that the guy who made it said it was "updating" on his page and removed the download link, but never updated it.
Here, it's on Filetrip for you to enjoy.
