The visuals look nice!
No sound really hurts the horror aspect. In such a small scope, it would be easy to implement, and would really elevate the experience. After the monster (very creepy btw, gj) came the second time, I started feeling a little stressed, knowing I have to catch more, because it's going to be back. That was really cool!
As per the fishing - the fish moves slow, until hitting the wall, when it speeds up significantly. Don't know whether it is intentional, but it threw me off a bit.
Also, when the bar reaches 100%, and you are supposed to be home, it resets. Some kind of an ending would be nice ^^
