Wow, an amazing game.
the mouse viewing is a bit finicky, but the Spacebar reset was a nice save.
some elements I didn't get, like the arrow at the top, but looks like a lot of effort was put here.
the arrow is pointing relative to the boat instead of the viewing direction, and is a bit confusing to look at with no edges(which way is forward...) I would Either put it on the minimap as a 2D arrow(I'm making exclusively 2D content... cause I suck at 3D) or make it change relatively to the viewing direction.
in both cases it should have an easy way to differentiate forward from backward.
