I played for 4 hours and concluded that this is not a game, it's an app to watch corny ads. gameplay is between a few sec and a few mins mostly bc you die easily followed by ads. click on store/rewards just because your curious?.. ads, power ups last longer? ads.. die in 2 seconds..ads. want to respawn?..ads. and it could be up to 2 mins long. it's easier for me to tell you that the only thing that doesn't have an add is the pause button. And the game really was fun. it's a shame what could have

fun game if it worked...Controls shotty! Speed button disappeared after 1st go. I don't see any instructions. Fish goes where he wants at times. Everything i earn during gameplay can only be collected if I buy something. 🤦‍♂️ There are way too many ads, & they're too long... some can't be skipped. Fix these & I could play this game for hours.

Cute, but flawed. Gameplay is OK, but could be slightly better, no way shape or form as advertised, and Ads fail to load despite being on WiFi or having a good connection: you're either required to watch an ad or pay 20 emeralds to respawn (no emeralds? Then you'll have to buy some!). Also misleading on unlocking new species: it will say "watch an ad" to unlock (the Pufferfish as an example), then you have to defeat a certain number of them. This game has LOTS of room for improvement honestly.
