Nice and relaxing game.
Very good presentation. Graphics were very pleasent, music was fitting and all around the aesthetic really added to the casual feeling of the game.
Boid mechanics were very fun to play with. Had a good time trying to find the optimum position to place the mouse to devour a ship without too many casualties and wrestling with the fish to get them to obey my whims!
For improvements, I think the camera positioning needs a bit of adjusting. It felt like when one fish would move far away from the rest, the camera would swing too much towards it, making it hard to see anything in the direction of travel. Perhaps base the position of the camera on the average position, so outlier fish don't skew it as much. Also, the boss is very, very hard, especially when it moves a high speeds. Finally, I think the hitbox on one of the larger boats is too small. My fish kept going inside it.
Overall, I do love a good Boid. And this game had some good ones. Great work and Congratulations to your whole team!
