Looks kewl. Edit the black gfx a bit at the tip of the harpoon a little and add some more texture into the arrow itself even though it consists of small pixels.
I had an idea about a system similiar to this but as a fisherman the cheapest item is a catch net that you catch anchovies in and minows then after selling the fish you buy a spear, not too much of a harpoon, the only difference is that a harpoon is for larger fish rather than small fish.
