Game

The store won’t load

Update where

Where is this new update that’s been pending for 2 years. I’ve maxed out all I can do…No expansions or other oceans available so nothing to work towards

Crashes so much you can’t play

The game is truly amazing. Exquisite animation, gorgeous score, and very educational in a very fun way. But after the latest “updates” I can’t even get the game to load to open it up. I’m very sad.

Apps cool but crashes

App crashes everytime I try to enter a New Haven. Redownload, and cleared out the app and still won’t work.

Great game, but…

I just unlocked the second reef area and it generates a tutorial where I have to go to that location, but every time I try to load in the game crashes.
