Nice game. I liked the feel of moving the tiles. There is a slight problem when I first enter a new puzzle. The movable tiles are below the screen! [0] (On Android, standard Chrome browser). It fixes itself if I rotate to landscape and then back to portrait.

So far I like the word list you've used. But I've only tried the easier days :p.
