I like this. I enjoyed how it has a simple easy to pick up premise and exploring was fun. I did reach the invisible wall on the West side. My ancor wouldn't accept the landing even though it was water, then figured it was a wall!
I liked that you could catch fish then throw them back. I think this is a cool exploring game and with more things to aim for like objectives or collecting things or even things to avoid could make it a compelling exploration game!
