Flappy Fish - Flappy Wings is a 2014 mobile game developed by CloudTeam and published by Digital Click. It features a fish called "Noi". Unlike other games of its league, the fish goes down when you tap the screen and back up once you stop touching the screen which makes it considerable harder to play.
Gameplay[]
If you find that you are used to Flappy Bird, you can control the fish far more easily by temporarily disabling auto-rotate on your device, then turning your phone upside down and controlling the Noi.
