Simply Delightful!
-As a small UI matter, I wasn't initially clear what the challenge levels were or that I could click on them in the World Complete screen
-It also would have been really cool if the levels rose and fell out of the mist, instead of the fade-out effect rising and falling with them
-Finally, it would have been super-neat if the cards looked like a bag of golf clubs you got to choose from
But these are all minor! It's a very thematic, unique, and never-to-frustrating puzzle game. (Well...never-too-frustrating as of World 5, at least). Perfect thing to cuddle up with while I wait to get over this stomach bug :)
