The menu is really charming and I like the style in general.
I played until the first dread admiral sent me to a watery grave.
It's really hard to tell when your cannonballs are actually aimed at the enemy ship and when they're gonna hit the water or pass over it, most of my run was me and two other ships circling each other and the only thing that took enemies out consistently was friendly fire.
Mines seem a bit inconsistent, one ship took three of them and was fine, idk if it's because they're low damage or if it might have some hit detection problem.
At one point it took two minutes from me killing the last ship on the screen and a new one showing up.
It needs some polish for sure but I can see what you're going for
