An interesting little game; I wasn’t able to get all that far, but I did manage to crunch up a few fish!
The sound design is a little confusing to me. I feel like the sounds didn’t quite center properly, as there were cases where I could’ve sworn there was a fish in front of me, but lunging did nothing. A learn sounds menu might’ve also been useful, or perhaps a list of all the new fish that played after a level-up.
I also managed to get the game to freeze at one point, with the arrow keys doing nothing anymore. But I would have to look into reproducing that before I can properly report it.
