Honestly sucks.

It forces me to watch ads to collect my level up rewards. I can’t opt out of ads bc I get it either way. What a dirty trick to compel players to watch ads.

Updates?

It would be nice if this game were updated with some improvements over time. It’s fun. The ads are so horrible though, and so inappropriate! How do I complain about a game I saw in an ad? Couples 3D. So distasteful!

Simple but fun.

I love the app but can you install an update where you can pay a small fee and remove the ads?

Too many ads

Too many ads to be relaxing.

Please add new fish!!

I love the game so much and find it so fun to play, but it would be better if they added more levels and more fish!!
