This is a fun game! I really enjoy these simple yet engaging arcade-type experiences, and I think you really nailed that vibe here. I also really like the art direction, especially with the color choices! Actually skewering the fish felt a little difficult at times due to the speed of the sailfish and how precisely you need to line yourself up to skewer the fish. I'd recommend either slowing down the fish a little (not too much, because I do like the sailfish's speed), making the hitbox of the fish's nose a bit larger, or making the skewerable area of the fishes larger (maybe some combination of all three).
Overall, nice work!
