We played this on our Thursday stream and I don't really have much feedback to give.
The fish controlled well but could be a little motion-sicky at times. The actual way the fish's body moved looked great. We enjoyed the amount of air time jumping out of the water caused. It was nice to see this as a 'score' at the end of the game because it did stand out while playing.
The ending. Yeah. That was brilliant. It tied the whole game together. Jack Black is a treasure.
Overall, a great entry for the jam.
