If you love aquatic animal you will like this game 🦑🐳🦈

I play this with my grandson who is not old enough to play it by himself. He loves that you get to win eggs and hatch them! The only part that needs to be adjusted is as someone else mentioned already... it’s very hard to unlock the green gems. Developers please change this and make it easier to win these.

Sure, there’s cool monsters to breed. The arena tournaments are pretty awesome but it’s not balanced out very well. I’ve been currently waiting for 3 days to save up 16M for ONE habitat. The price of planting food, how much food costs for feedings, and how much you generate per minute is a struggle. Besides this, there is no guidance. There’s no information in the market telling you what items are for. Example, you HAVE to buy a temple to upgrade your monster past level 10. It’s a cute game but man, I don’t want to wait WEEKS to advance. Also, when I attempted logging into FB for 10 gems there was an error stating my app didn’t have permission. I contacted their FB page and have yet to hear back. 🤷🏻‍♀️
