This is possibly the best boggle like game I've ever played, and it's a lot like PuzzleQuest so I imagine i'll find the right rhythm as I level up. It can be difficult to try and watch the battle at the same time as making words, but you kinda get the hang of it.
As others mentioned, it's an intense game, but I really like the change of pace from all the other word games out there. The art is really pretty, the story seems well written (though I haven't been able to unlock much of it yet in the demo), and I'm surely a little intimidated! But I'm excited to see what all the modes are about.
