Fun little game. Especially the comical movement of the boat. I adore that you decided it is fine that the boat can go over land, but will just be jank. And that when it eventually touches water, it always rights itself is wonderfully done. Unfortunately, it does mean that you can reach the world edge and fall into the void. (Maybe do put some walls up).
The gameplay loop was fine. Shooting the items felt quite slow, diminishing the impact shooting your ware are supposed to have. But overall, a nice experience.
