Liked the puzzles. The first one (with RBS) took me a short while, but that's probably me rather than it. The one with the two goblins where one drops the fireball was also a bit odd (not sure how it's supposed to work). Looking forward to more of these.
And, as has been said, the new sparklies have less visibility. I wonder what it would look like if they had the current swirly mist on top of the old single color dot in the middle.
And yes, the blacksmith and something overlap, and they also still cause some confusion when selecting preps. Technicaly, the blacksmith, gods and locker preps are really close to each other creating a cluster, and since there are no labels or bordered boxes for groups of preps it is bound to be confusing (at least once you unlock enough of them).
So if, just for the sake of the prep screen, the god prep icon group could be moved a bit to the right, and the locker icon group a bit to the bottom right diagonaly, I suppose it would be a lot better.
In short:
Current cluster:
What I'd preffer:
The bazzar I moved simply for aesthetics sake, as it would probably benefit from moving the entire building art a little if it's possible. There's space for it. But the other ones probably should be moved, and since the groups are so large, they probably don't need to be right on top of the buildings, since you can't see the buildings because of them.
Leaving the two big groups where they are and just moving the blacksmith selection to the upper right would probably work as well, and is easier. Should've thought about it before I made the mockup...
