I have solved all 16 puzzles and have the max pop. What now? Is there anything else I can do?

What you decide to do depends on what you like about the game.

Once you complete all the puzzles, there aren't any more 'official goals' left in the game. There are still many more island events that you haven't seen, which will change the circumstances in the game - and they present some interesting choices to make. There are also a lot of villager behaviors that you may not have seen unless you've spent a fair amount of time 'peep watching.'

On the other hand, the village can get pretty crowded in the later stages of the game, and many people start over to try some new strategies, or play the game on a different setting. I've played dozens of different games and chased some fun challenges that I set for myself - like solving puzzles as early as possible in the game, or finishing all of the puzzles (except the graveyard) without any of my villagers dying. There are many interesting things to do with the game!

ive just solved all the puzzles too and now am somewhat let down that theres nothing else to do, especially concerning the newly uncovered cave. so id have to say its a great game but a [censored] ending!!!

Totally agree...I really thought once we opened the cave you would continue in new and unexplored areas of the Island. I am Not too happy now with this game...

You can drag a villager onto the cave and see what's inside....

Doesnt the site say you can explore other areas

i want to go to greener pastures

i just want to see the inside of the cave & find out who/what the eyes belong to.need more areas to explore like the cave & what ever is beyond that.we need an expansion pack for the end.

I am hopeing for a Part2 that takes some of the villagers through the cave to another part of the island to start all over again,

I found out that someone is swimming in the lagoon!
