Comments on Underwater Idle Simulator for Android

★★★★★ Kyle Mendoza · May 29, 2026
Seahorse! Entertaining. I am ☺ smile. Here.
★★★★★ Akhilesh Pandey · Sep 4, 2026
Can you pls add this thing like the cyclopedia where all the fish you collected appers in it, and also you can learn about fish too, and also it has some real life images of it too and facts too and add freshwater fish too and add wallpapers for tanks and plants too
★★★★★ Tina Ewing-Wilson · Aug 6, 2026
It's cute, but there are too many ads. However, they redeem themselves by offering an ad free purchase option that truly is ad free
★☆☆☆☆ Jane Whyte · Jul 7, 2026
Barely a minute into the game before a forced ad pops up and that's not to mention the mandatory ads you need to watch to upgrade things or speed things along
★☆☆☆☆ Sarah Green · Jun 11, 2026
About tank 18, the game played an ad and shut down. When I reopened the game, all progress was deleted and started me back to the 1st tank.
★☆☆☆☆ Machell Perryman · Jun 6, 2026
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.
