Notes

This is one I remember clearly as a very early DS game I owned as a kid. It's kind of a medium puzzle game. Clear lines of blocks by swapping them between black and white. Two modes, an arcadey mode where lines drop and you have to clear them as fast as possible, and a puzzle mode with preset configurations to clear.

Not very stunning. Also a puzzle game without a story or credits as far as I can tell.
