This was pretty fun! And as someone who also programmed 2d waves, I appreciate the effort involved. 

Three things to consider improving: (1) Jumping the boats is a lot of fun; probably the best part of the game. You should get bonus points or a speed-boost for doing it. (2) If the AI dies from a shark, they should respawn. Having the game end because the AI is dumb doesn't feel great. (3) It's possible to get stuck on the boats. Maybe the dolphin needs a way to flop/jump off.

I appreciated the player vs AI mode, it remembered me the good times playing the micromachines game with two players, that is fun.

Graphics are simple but functional, and the controls are working fine. It is true that the gameplay becomes dull after a few seconds, I believe the mechanic of jumping above the sea should be rewarded or motivated more, because it is interesting.

Thanks for being open about the AI usage and how it was used. I personally have no issues about AI being used for art in jam games - unless it is not disclosed. Then you are always just left questioning what is actually AI and what is not.

The generated art in this game is fine but it lacks cohesion. Color-palette, pixel sizes, and resolution are a bit all over the place. But that is to be expected with AI art, and I feel people are slowly getting better using AI for art in more cohesive ways.

The highlight mechanic of this game is definitely the jumping. It just feels fun - just like I imagine dolphins feeling when they do that in real life.

Aside from that, the game is quite basic and there is not much motivating the player to play it for longer. It does not really change the longer you go and it is very easy to get good distances just by swimming near the surface. I also got stuck on top of boats a couple of times which was a bit annoying.

But overall, thanks for a solid entry and bonus points for disclosing the AI usage.

I can't believe this soundtrack is AI-generated; it's incredible. I'd give it a very high audio score, even though it's AI-generated.

However, it's a pity that besides the dolphins, the sharks have no animations, and there aren't any other types of enemies. At first, I thought I wasn't running far enough, so I tried running further to find other enemies. I ran nearly 40nm, and it seems that's all there is to the game.

Adding some other items and enemies would make it more interesting. If you want to make multiplayer battles more fun, you could take inspiration from Mario Kart—that's my suggestion.

Also, I expected there would be waves, but there weren't. If the waves could help me get over the boats, it would better convey the theme (I tried to get over them, but I ended up getting stuck on them, my speed dropped to 0, and I couldn't do anything).

it would be good if the speed boost just kept stacking up in the single play mode, i think it would be more engaging to be able to get to ridicules speeds from eating the fish constantly.

good concept and nice clean work.
