This was a fun experience, the gameplay felt nice and smooth, I like how the boat animated as it moved left and right, and how it went underwater with the anchor, the text dialog was also comical and entertaining.
It's also nice that every upgrade also adds a new obstacle/enemy trying to take your gold, made the gameplay more interesting.
Polish looks great, as others mentioned the aesthetic is quite pleasing and feels very arcady.
I could see this becoming a full game, with more content and challenges
Congrats on the submission and well done!
