I have enjoyed every minute of VV3; struggling for survival (much more so than the previous two) and have found my way through all the puzzles unaided except for the Sharks - but I have downloaded the Guide now, so if I decide to cheat/spoil, I will look at that to find out how to finish the puzzles.
The variety of the villagers and the gameplay is great again, and I didn't find any bugs except that sometimes the area where you dropped your villager dropped into another area below or above.
I have five games going at once to fix that lag time of VV time, which again never ticks over as quickly as you'd like, and pause games when I'm at work or need rest. If my villagers happen to die, well, I just start another game up and usually complete puzzles and tasks much, much quicker.
Congrats to everyone involved. Job well done.
