I did a playthrough of your demo.
Apparently you can just move through the water without making a bridge, also I'm not sure how the fishing works since it doesn't tell me if I actually caught a fish or not.

Thank you so much for playing it.
The fishing thing seems to be a bug, in its current stage it is supposed to print out text telling you you caught a fish if you did, and if it got away if you didn't. However from your game-play it's evident that didn't happen and I'm unsure why, this will be fixed when a proper "wow you caught a fish" screen is added.
As for the water thing, I'm absolutely clueless as to why it creates the collision box for the begining of the animation and the end frame of the animation. It is what it is and I'm sure is a simple fix, as most of these seem to be. Thank you again for taking your time out to make a vid of your play-through, seeing how other people interact with my game helps me immensely.
