What real reviews say

★ Lame The game makes no sense at all. You’re bigger and a higher level, but you easily get killed by someone weaker. The graphics are terrible, you can’t even tell if you’re attacking someone or what’s happening. They expect you to watch ads for EVERYTHING. Don’t waste the $2.99 to remove ads, it only

★★★★★ Awesome Awesome game merge your fish and get bigger and better super entertaining

★★★ Holy ads 2 ads in a row? Come on guys. I close the app and restart it. Sometimes I don't restart it at all. I'm so sick of intrusive ads that I don't want to bother downloading "free" games anymore. The game would be fun if I could actually PLAY IT.
