Strong ambience and aestethic here, good job! I like the idea of fishing wile having to look over your shoulder, but not sure what, if anything, was supposed to happen back there? I caught several fishes, sounds like the further you go the harder it gets, but other than that nothing hapenned. I did notice your comment saying this was unfinished.
This seems like a basic, but solid base to a very nice and creepy cozy game.
