Ratings and reviews

Too many forced ads!! One minute of game play then.. forced ad.. repeat. I understand that devs need an income but this game expects you to spend $22 (Australian) PER WEEK for VIP which removes the forced ads. I really wanted to give this game a chance but I spent more time watching ads than playing the game. Uninstalled. I won't be back unless you remove forced ads.

Forced ads unless you pay a subscription. The moment you start the app, you're met with an offer to pay a sub. Get some shame.

the game was so fun in first playing. but when you complete all quest, upgrades and maxx level getting wierd and boring. no more new maps. new upgrade new fish ect... is that all?? so wierd.
