Really love the art style, it's super eye-catching and unique! The whole game just oozes personality. The enemies are great too, the cannon pirate was easily my favorite, and the transition screen was awesome. The looping song was a bit loud for me so I ended up muting it after a while, but it's a nice track.
Not sure if it was something I did, but at one point I was taking damage even though there were no enemies on screen.
Really nice job overall!
