This was fun, I like games that are how good can you get at the game to rack up a high score. I especially liked the animation of the water as the boats moved around, that was cool. I don't know what other engines were used in games I've played so far in the jam, but it felt like unique to have it done in Unity.

What a cool galleon (it is one, right?)

One request: please add the controls to the game page! It took me a couple of minutes to figure out that I had to move with WASD (not arrows) and shoot with Q and E. At first I thought your game was broken!

The shooting direction also confused me a bit. Maybe a small HUD indicator showing Q and E on each side of the ship would help.

Apart from that, the art is cool and the game loop is fun, even if simple. Nice work!
