I like this game. Very cute and had a lot of potential. I haven't beaten the game yet but from what I have played the tank system is a little annoying. In your first room of your shop you get four fish tanks. 2 large ones that hold 4 small fish and 2 large fish and 2 small tanks that hold 3 small fish and one medium fish. So that totals about 20 fish. But there are more than 20 types of fish. You eventually are forced to either hoard new fish or sell them and I really don't like that.

So, it's a pretty fun game, but I completed it too fast. It only took maybe 7 or 8 hours if that, over the course of three days to fully upgrade the aquarium and collect all the fish. Now I'm sitting at almost 500,000 cash with nothing else to do. Just wish there was more to upgrade, or maybe sell your current aquarium for a bigger one with a slight cash bonus.

Avoid! It's a fun game and all, I even paid for ad free! (£9.99!) the big problem with this game is twice now I've made a lot of progress and when I've closed the game and reopened it later its lost lots of my progress!! I had opened and upgraded the otter room and tentacle room but now both rooms are gone along with lots of other upgrades I made to other rooms! Pretty angry right now! Huge waste of time!!
