Ratings and reviews

I really enjoyed playing this game for the 24 hours it worked. For some reason, it's become impossible to operate. I log in, and I can see my haven and all the sea creatures moving around, but I'm unable to interact with anything. Redownloading and restarting my phone have yielded no results. Edit: Changed to 3 stars because I can play the game about half the day before it locks up again. I've seen reviews where people get locked out of a haven permanently. Will change to 5 stars if fixed.

I wasn't able to play long enough to give a good review, hence one star. Every time I try to enter my haven I get a "fetch haven failed" error (might have different wording). Otherwise... I like the stylization. The game isn't very engaging, but feels more like a game you check for a few minutes during a work/school break, which is fine. I don't get how playing a game helps organizations, I didn't see any info explaining it while I played; I would like to see that added, and to be able to play.

The game is beautiful, and it's sorta fun to play. Although the lag is bad, it makes it difficult to defeat the enemies. I tried uninstalling the game, resetting my phone, but still nothing. Now, everything I try to play in my haven, it would freeze for a long time. Pls fix it. I really like the game T_T
