User Reviews
Really pushy with the ad spam even very early on, and even "optional" ads can't be skipped, it still forces watching them anyway, you just don't get the reward then. Gameplay is fairly standard idle progression game, but with far more artificial gates that require constantly watching ads to bypass them. It'd be middle quality of a game with zero ads, but it's definitely below average by pushing them so hard constantly. You can do better, try something like CIFI instead.
The game itself is fine. But there are too much ads. Almost everything trigger ads every other click.
No way to turn off sound. More importantly, no way to turn off vibration. Cannot stand the stupid vibration on these games. Didn't even get to the part with 'too many ads'. Uninstall.
fun game but every 30-90 seconds I'm getting forced ads on top of having to watch ads to star up aquariums. this is a click bait game DON'T DOWNLOAD
