FWOP

There are only 2 buttons: Flop left and flop right.  You can use the arrow keys, mouse buttons, or A and D.

Post-jam updates:

Now you can use a controller!  Triggers and sticks will both flop left and right. There's also an optional mouse analog control (disabled by default) where the mouse how far left or right from the center of the screen the mouse cursor is determines how much left or right the fish will flop.

Some notes:
I used freesound.org assets by ralph.whitehead and davidgtr1 just for the ambient background loop.  All other assets were created by me.  Bot524 helped with the water shader.  GobsmackGoose came up with the name idea of "FWOP" (a nice homage to QWOP, an older Bennett Foddy game).  I was originally calling it Flappy Fish.

Tools used: Godot Engine, blender, Reaper, Pianoteq.

The game may be stuttery when played in web, so I would recommend downloading the native Windows or Linux version for a better fish flopping experience.
