well im a beta tester for LDW and had it before big fish did, and if they are ahead of me....well..what more can i say

Its a little too obvious in most cases.
If you look at 90% of the games on the market you will see vast similarities in sequels to games. Its not a new game or a new concept its part 2. I mean the game costs what 20$ and your complaining. Lets looks at a couple other games.
Bejeweled. I believe its like 19.95 most places. Bejeweled 2, holy cow its the same game but the jewels look more detailed and an extra puzzle or mode. Warcraft 1 2 and 3. Holy cow each new game came out with a couple new units and a building or two, and a diff map scenario. These games are still wildly popular. Counter strike...many different forms...all the same game, same ideas, concepts, and strategies. Half life...same game, updated graphics, couple new guns...Point being i think the people got more than you'd expect from most sequels in any genre of gameplay. The island looks nicer, the behaviors are improved, tons of added behavior models, lots of additions in skills. Many new puzzles, added collectables with bonuses for completion. 3 puzzles are the same you say. There are 16 puzzles to solve. 3 is a rather meager number. I might agree if it was 8 or more of the same thing. Game takes longer to beat, many added events.
The biggest problem is everyone hyped up this game so much that some people are sadly dissappointed because they built up such an idea of what "they" would have liked to see and dont really see the game overall and that there are vast more bonuses to the game and some things added that werent even requested. Im sorry that you dislike the game...and this is my last post on the topic.
I'd say simply move along.
