The game looks really nice and it was fun to play! After 3 minutes I started to get a little repetitive, but I think it was fun. The octopus is really strong haha I had a hard time with them.
Here was my run:

Fun game! I really liked when I could shoot boats on both sides at the same time. Good job! This was my score, very little haha

I got some little lag but it was unclear why and it went away after a while. This makes me think that there are objects or effects that are being instantiated for the first time. I had a similar thing in another project in Godot.
Great game! Had fun playing it, but I could beat the main quest in the second run.
I think the mechanic is fun and it is a great game. I will look to see how this evolves but even if there is no change to the game I think it is worth it.
Thinking about what could improve, I wanted to be able to organize my board while the game is paused or create some way to make it easier to manage a big board as it can get messy. Basically I started using the time I had to sell extra cards to organize my board.
Keep up the good work. The art of the game is also great!
