Just played with it for a few minutes, I liked it! The only bit that occasionally tripped me up was going diagonally in my word construction, but I got the hang of it after a few rounds.
One thing that may make this easier is beveling the edges of the tiles slightly so you don't accidentally select letters on either side of the diagonal unintentionally.
