Really enjoying this so far. The usual nimblebit Polish is there and it's quite challenging. I think having a shuffle tiles button outside of the hint menu would be beneficial...not sure if that would change the gameplay or the challenge of the game. Sometimes when I shuffle I want to hit it a couple times, having it in the menu prevents that. Trivial, I know, but it's something that id like to see. Shuffling should be quick and easy. Other than that, so far I love the game. It's a great challenge. Already had a few people looking over my shoulder asking me what it is and handed it to them to try it out. Everyone seems to enjoy it!
