Yeah, so I'd take the rod and equip it. I think it would then ask what kind of bait I wanted to use. I'd pick the sand roach, then cast it into the water. I couldn't cast it very far, so I wasn't sure if I was supposed to get it near the schools of fish in the water. Regardless, nothing would happen, and WASD would move the bobber and reel it in. I was left unsure if I was doing something wrong, or missing a key to cast further, or what. I kept on expecting to be able to wind up casting my line similarly to how you can wind up a swing with the scythe, but it wouldn't work.
