Good game!
I like the idea of saving people with a boat, while the art style is minimalist and fitting. UI needs some improvement regarding design to fit the overall art style I think.
The game loop is clear and functional and fits the theme perfectly, although some more feedback would be nice (radius of the boar picking up people and saving them for instance). The controls work fine, the movement of the boat is fine as well, just a little hard in my opinion.
For me there was no music or SFX which is a pity I think. A game profits from sounds sooo much!
Overall a good entry!
