Fun idea!
I love the hand-drawn graphics (especially the ship) and the gameplay is quite intriguing. Hitboxes felt pretty fair too.
Had to quit at the canons though, since I had no Idea where to go to escape those pesky pirates. The game either could be easier / have an optional easy mode or the time between respawns could be reduced to make dying a bit less of a punishment imo.
But up to that point the game was fun, nice work!
