That was very fun!
My strategy ended up being bouncing back and forth between the land to keep my broadsides going toward the enemies, and I was able to last until tons of battleships started spawning in.
I suggest continuing to add some more enemy and upgrade variety.
The ship handling and drifting mechanics were cool, it reminded me of a driving game I made for Brackeys game jam called Nuke n Rally.
Very nice sound and art assets, this felt like a very polished game!
