I was a little confused about what I had to do at first, but the moment I figured out, it was a huge LOL moment and I was smiling the rest of the time I played. With some polishing up, this would be a great touch screen game in an app store!
Also, I can't imagine how much time and thought you had to put into the way the hose wrapped around things. I was just reading a whole article on the rope physics in The Last of Us 2, and here you pulled off an (albeit simpler) version in two days! Nice. :-)
As it is, I didn't have much desire to keep playing for too long--the "out of control" nature of the controls don't jibe well with my level of patience--but I think adding, say, an arrow that indicates the direction and force of the water may help better convey how your farmer will move.
