Professor Layton and the Unwound Future

Just started playing this. I've gone through about 7-8 puzzles now and the game's looking pretty sweet. Much the same as the other games in the series, of course, but the puzzles do seem slightly trickier. I've already had to use a hint coin :(. I like the improvements made to the Memo function, though I can still imagine myself grabbing a pen and paper for the later puzzles.

It's still early days though. I've yet to really get into the meat of the game. Anyone else playing this at the moment?

I've not played any Professor Layton games, but I just wanted to say that this game has a deeply sinister title to me. It's like Professor Layton and the Shadow over Innsmouth or Professor Layton and the Tell-Tale Heart, only even worse, because it involves the impending end of time itself.

I've always wanted to have a look at these games, but I never have...
They're always too expensive, and I'm always too stingy.
I'm assuming you'd recommend them?
